production: opencd.css hardened — zero magic numbers, all --cd-* vars, ASW semantic, Nous auth copied

opencd: murdock prototype — opencd.css + three templates (jewel-case, leaflet, back-tray)
Prototype build incorporating Amy's gate review findings: - Custom --cd-surface-* tokens (oklch), not Open Props - Custom --cd-grid-* tokens via gray-3/gray-2 - --cd-scale: 1 = default 2x display scale, all dims calc() - --cd-font-label using font-neo-grotesque for spine legibility Files: - opencd.css (622 lines) — full monolith with variables, reset, components, grid overlays, advisory badge, print styles, responsive containers - templates/jewel-case.html — front jewel case with spine + disc + advisory - templates/leaflet.html — 4-page booklet with page-turn navigation - templates/back-tray.html — back tray with tracklist, dual spines, grid GPG: ABE295FFEB4571F8 — H.M.

+# MISSION_BRIEF.md — OpenCD Gate Review
+
+> **Agent:** Amy Amanda "Triple A" Allen — Intelligence & Quality Gate  
+> **Mission:** Gate review of RECON.md (Face) against DESIGN.md (Hannibal)  
+> **Status:** CONCERNS — see §Verdict  
+> **Date:** 2026-05-25  
+> **Context:** Pre-build quality gate (Phase 2 of implementation sequence, cf. DESIGN.md §7)
+
+---
+
+## I. Scope of Review
+
+This gate validates three things before Murdock begins building `_variables.css`:
+
+1. **Token accuracy** — Does every Open Props mapping in DESIGN.md match the source-verified values from RECON.md?
+2. **Dimension accuracy** — Are the CD physical measurements correct and consistently applied?
+3. **Pattern alignment** — Do the ASW, trentuna, and Human Advisory references translate correctly to the architecture?
+4. **Coverage** — Did Face answer all five questions Hannibal posed in DESIGN.md §6?
+
+---
+
+## II. Source Verification Cross-Reference
+
+### A. Token Mapping Table (DESIGN.md §2 → RECON.md Q1)
+
+| DESIGN.md Mapping | RECON Finding | Verdict |
+|---|---|---|
+| `--size-fluid-1` = `clamp(.5rem, 1vw, 1rem)` | ✅ Confirmed | PASS |
+| `--size-fluid-2` = `clamp(1rem, 2vw, 1.5rem)` | ✅ Confirmed | PASS |
+| `--size-fluid-3` = `clamp(1.5rem, 3vw, 2rem)` | ✅ Confirmed | PASS |
+| `--font-size-fluid-1` = `clamp(1rem, 4vw, 1.5rem)` | ✅ Confirmed | PASS |
+| `--font-size-fluid-2` = `clamp(1.5rem, 6vw, 2.5rem)` | ✅ Confirmed | PASS |
+| `--font-size-fluid-3` = `clamp(2rem, 9vw, 3.5rem)` | ✅ Confirmed | PASS |
+| `--font-sans` = system-ui, sans-serif | ✅ Confirmed | PASS |

+| `--radius-2` (5px) | ✅ Confirmed | PASS |
+| `--radius-3` (1rem) | ✅ Confirmed | PASS |
+| `--gray-1` through `--gray-12` | ✅ Confirmed | PASS |
+
+### B. CD Dimensions (DESIGN.md §2 → RECON.md Q2)
+
+| Dimension | Source (ISO 15727) | DESIGN.md Value | Verdict |
+|---|---|---|---|
+| Jewel case width | 142 mm | 280 px (2×) | PASS |
+| Jewel case height | 125 mm | 245 px (2×) | PASS |
+| Disc diameter | Ø 120 mm | 240 px (2×) | PASS |
+| Leaflet page | 120 × 120 mm | 240 px (2×) | PASS |
+| Spine width | ~7 mm | 14 px (2×) | PASS |
+| Open width | 284 mm | 560 px (2×) | PASS |
+
+### C. Coverage of Hannibal's Five Questions (DESIGN.md §6)
+
+| Question | RECON Section | Answer Quality | Verdict |
+|---|---|---|---|
+| Q1: Open Props Token Audit | Q1 (lines 10–121) | Full source-verified table, import paths, new tokens | PASS |
+| Q2: CD Jewel Case Dimensions | Q2 (lines 124–180) | ISO standard, 2× scale analysis, region check, tray paper layout | PASS |
+| Q3: ASW Design Patterns | Q3 (lines 183–266) | 11-layer architecture, semantic HTML examples, data-attribute vocabulary, token system | PASS |
+| Q4: CD Packaging References | Q4 (lines 269–336) | 5 examples, grid analysis, PA badge specs | PASS |
+| Q5: trentuna.com Aesthetic | Q5 (lines 339–390) | Fonts, palette, grid approach, content structure, lessons | PASS |
+
+**Coverage verdict: PASS** — All five questions answered with source-verified evidence.
+
+---
+
+## III. Critical Findings — Issues Requiring Correction
+
+These are discrepancies between what DESIGN.md assumes and what RECON.md proved to be true. **These must be resolved before Murdock builds `_variables.css`.**
+
+### Finding #1: `--surface-*` tokens are NOT from Open Props
+
+**Evidence:** RECON.md Q3 (lines 252–253) demonstrates `--surface`, `--surface-1` through `--surface-4` are ASW custom tokens defined as `oklch()` with `--palette-hue` tinting. Open Props has no surface tokens.
+
+**Impact:** DESIGN.md §2 maps `--surface-1` → `--cd-tray-bg`, `--surface-2` → `--cd-tray-bg-raised`, `--surface-3` → `--cd-tray-bg-sunken`, `--surface-4` → `--cd-spine-bg`. These will silently resolve to `unset` if not explicitly defined.
+
+**Correction:** Define `--cd-surface-1` through `--cd-surface-4` directly in `_variables.css` following the ASW pattern:
+```css
+--cd-surface-1: oklch(30% .015 265);
+--cd-surface-2: oklch(35% .015 265);
+--cd-surface-3: oklch(40% .015 265);
+--cd-surface-4: oklch(15% .01 265);
+```
+(Values to be finalized by Murdock — this is the structural requirement.)
+
+### Finding #2: `--grid-*` tokens don't exist in Open Props
+
+**Evidence:** RECON.md Cross-Reference (lines 105, 403) explicitly notes `--grid-1` and `--grid-2` are NOT Open Props tokens.
+
+**Impact:** DESIGN.md §2 maps `--grid-1` → `--cd-grid-color` and `--grid-2` → `--cd-grid-color-alt`. These resolve to nothing.
+
+**Correction:** Define as custom properties using gray shades that do exist in Open Props:
+```css
+--cd-grid-color:     var(--gray-3);
+--cd-grid-color-alt: var(--gray-2);
+```
+
+### Finding #3: `--cd-scale` semantics differ between DESIGN.md and RECON.md
+
+**Evidence:** 
+- RECON.md (lines 148–157): Recommends `--cd-scale: 1` as default, where `1 = 2×` scale. Formula `calc(142px * var(--cd-scale))` where scale=1 gives 142px (which is NOT 2×).
+- DESIGN.md (line 265): `--cd-scale: 2` where value=2 means "multiply physical mm by this to get px."
+
+**Impact:** Inconsistency. If a user reads both documents, they'll get different behavior. Under DESIGN's scheme, `--cd-scale: 2` gives 284px jewel width (not 280px as documented). Under RECON's, `--cd-scale: 1` gives 142px (wrong).
+
+**Correction needed:** Pick ONE semantics and make it explicit:
+- Option A: `--cd-scale: 1` = physical mm → px (1:1). Default 1 gives 142px. If you want 2×, set `--cd-scale: 2`.
+- Option B: `--cd-scale: 1` = "1 unit of scale" where base=2×. Uses a pre-calibrated formula: `calc(142px * var(--cd-scale))` where scale=1 gives 280px because the base values are already in px at 2×.
+
+**Recommendation:** Option A is cleaner and more intuitive for users. But the entire DESIGN.md and README hardcode 280px/245px/240px values. If we change the semantics, every dimension formula changes. **Stick with DESIGN.md's current approach** (`--cd-scale: 2` means 2× multiplier on mm→px conversion) but make the formula explicitly mm→px:
+```css
+--cd-jewel-width: calc(142mm * var(--cd-scale) * 3.78px / 1mm); /* 3.78px/mm at 96dpi */
+/* Or simpler: hardcode 2× values and multiply --cd-scale against those */
+```
+OR, simplest solution that avoids the scaling math entirely:
+```css
+--cd-scale: 1; /* 1 = default 2× scale. Set to 0.5 for 1×, 2 for 4× */
+--cd-jewel-width: calc(280px * var(--cd-scale));
+```
+Document this clearly. **Action: update both DESIGN.md and `_variables.css` to use this unambiguous formula.**
+
+### Finding #4: Font recommendation — consider `--font-neo-grotesque` for spine labels
+
+**Evidence:** RECON.md Q1 (line 74) and Cross-Reference (line 407) recommend `--font-neo-grotesque` (Inter → Roboto → Helvetica Neue) over `--font-sans` (system-ui) for spine labels. System-ui varies significantly across platforms (Chicago on macOS, Segoe UI on Windows).
+
+**Impact:** Low severity. System-ui is readable, but spine labels benefit from the consistent, designed look of Inter/Roboto.
+
+**Correction:** Non-blocking recommendation. Update DESIGN.md §2 or `_variables.css` to use `--font-neo-grotesque` for `--cd-font-label`:
+```css
+--cd-font-label: var(--font-neo-grotesque);
+```
+
+---
+
+## IV. Additional Observations (Non-Critical)
+
+### ASW Gap Fills Worth Noting
+RECON.md (lines 258–260) identifies `--space-3` (0.75rem) and `--text-sm` (0.875rem) as values Open Props doesn't natively provide. If OpenCD needs these for spacing/sizing between Open Props' discrete steps, define them alongside the `--cd-*` tokens.
+
+### New Open Props Features for Consideration
+RECON.md (lines 115–121) documents: easings (`--ease-elastic-*`), animations (21 presets), aspect ratios, line heights. The `--ease-flip` token in DESIGN.md currently uses a raw `cubic-bezier()`; consider mapping it to an Open Props easing token if one matches.
+
+### Human Advisory Badge — Red/Black Variant
+RECON.md (lines 297–298) suggests supporting both classic black/white and OpenCD red/black variants. DESIGN.md currently only specifies red (`--cd-advisory-red`). Consider adding `--cd-advisory-scheme` to toggle.
+
+### Visible Grid — Two Sizes
+DESIGN.md calls for `.cd-grid--fine` (denser tray) and `.cd-grid--coarse` (leaflet). RECON.md provides the base 8px grid formula. The grid sizes should be documented as variables:
+```css
+--cd-grid-fine: 4px;
+--cd-grid-coarse: 8px;
+```
+
+---
+
+## V. Verdict
+
+**Overall: CONCERNS**
+
+| Dimension | Rating | Detail |
+|---|---|---|
+| Token accuracy | ✅ PASS | All Open Props tokens source-verified |
+| Dimension accuracy | ✅ PASS | ISO 15727 confirmed, no regional variance |
+| Design alignment | ⚠️ CONCERNS | 4 issues (fnd #1–#4) require correction |
+| Recon coverage | ✅ PASS | All 5 questions answered thoroughly |
+| Source verification | ✅ PASS | Every source accessed and cross-referenced |
+| Precision | ⚠️ CONCERNS | `--cd-scale` semantics ambiguous across docs |
+
+### Gate Decisions
+
+| Gate | Status | Action Required |
+|---|---|---|
+| **Pre-build Gate** | **CONCERNS** | Resolve findings #1–#3 before Murdock builds `_variables.css`. Finding #4 is advisory. |
+
+### Corrective Action Items (Ordered by Priority)
+
+1. **HIGH** — Define `--cd-surface-1` through `--cd-surface-4` explicitly in `_variables.css` (not inherited from Open Props)
+2. **HIGH** — Define `--cd-grid-color` and `--cd-grid-color-alt` using `var(--gray-3)` / `var(--gray-2)` (not from non-existent Open Props tokens)
+3. **HIGH** — Resolve `--cd-scale` semantics: pick one formula, update both DESIGN.md and README.md to match. The recommended approach is `--cd-scale` as a multiplier on the hardcoded 2× values.
+4. **LOW** — Consider `--font-neo-grotesque` for spine labels instead of `--font-sans`

+> **Mission:** Research Open Props, CD physical specs, ASW patterns, trentuna.com aesthetic, CD packaging references  
+> **Date:** 2026-05-25  
+> **Context:** Parent task [t_2c57546a] — DESIGN.md architecture plan calls for this recon before implementation
+

+
+## Q1: Open Props v2 Token Audit
+
+**Source verified:** `open-props.style` + `github.com/argyleink/open-props` (main branch source files)
+
+### Import Paths (Current)
+
+| Method | Code |
+|--------|------|
+| **CDN (CSS)** | `@import "https://unpkg.com/open-props";` |
+| **CDN (HTML link)** | `<link rel="stylesheet" href="https://unpkg.com/open-props"/>` |
+| **npm** | `npm install open-props` then `@import "open-props/style";` |
+| **PostCSS JIT** | `postcss-jit-props` plugin — only ships used props |
+| **Design Tokens** | JSON at `https://unpkg.com/open-props/open-props.tokens.json` |
+
+**Recommendation:** Use `@import "https://unpkg.com/open-props"` for the CDN path (already in DESIGN.md). For npm builds, use `@import "open-props/style"`.
+

+| `--font-size-fluid-3` | clamp(2rem, 9vw, 3.5rem) |
+
+#### Font Stacks (`props.fonts.js`)
+
+| Token | Stack |
+|-------|-------|
+| `--font-system-ui` | system-ui, sans-serif |
+| `--font-neo-grotesque` | Inter, Roboto, Helvetica Neue, Arial Nova, Nimbus Sans, Arial, sans-serif |

+
+### Critical Findings for the README → DESIGN.md Mapping Table
+
+| README Claim | Actual Open Props Status | Action Needed |
+|-------------|------------------------|---------------|
+| `--surface-1` through `--surface-4` | **NOT in Open Props.** These are ASW custom tokens. Open Props provides `--color-1` through `--color-16` (palette-hue driven oklch scale) and individual gray shades. | Use ASW-style semantic aliases or define `--cd-surface-*` directly |
+| `--grid-...` | **NOT in Open Props.** No grid-related tokens exist. | Must be custom — use `repeating-linear-gradient` following trentuna.com's pattern |
+| `--red-6` / `--red-7` | **Confirmed.** `--red-6` and `--red-7` exist in the red scale. | Good to use as-is |
+| `--shadow-2` / `--shadow-3` | **Confirmed.** Exact values verified above. | Good to use |
+| `--font-size-fluid-1` through `--font-size-fluid-3` | **Confirmed.** Values verified. | Good |
+| `--size-fluid-1` through `--size-fluid-3` | **Confirmed.** Values verified. | Good |
+| `--font-sans` | `var(--font-system-ui)` = system-ui, sans-serif | Consider `--font-neo-grotesque` for better label aesthetics |
+| `--font-serif` | `ui-serif, serif` | Good for leaflet body |
+
+### New/Notable Open Props Tokens Since README Was Written
+
+- **Easings:** `--ease-elastic-*`, `--ease-spring-1..5`, `--ease-bounce-1..5`, Robert Penner equations (`--ease-circ-*`, `--ease-cubic-*`)
+- **Animations (21):** `--animation-fade-in/out`, `--animation-slide-*`, `--animation-shake-*`, `--animation-spin`, `--animation-ping`, `--animation-blink`, `--animation-float`, `--animation-bounce`, `--animation-pulse`
+- **Aspect ratios:** `--ratio-square`, `--ratio-landscape`, `--ratio-golden`, `--ratio-widescreen`
+- **Font line heights:** `--font-lineheight-00` (.95) through `--font-lineheight-5` (2)
+- **Letter spacing:** `--font-letterspacing-0` (-.05em) through `--font-letterspacing-7` (1em)
+- **Design Tokens export:** JSON, Figma, Style Dictionary formats available via unpkg

+
+## Q2: CD Jewel Case Physical Dimensions
+
+### Standard Dimensions (ISO 15727)
+
+| Component | Metric | Imperial | Notes |
+|-----------|--------|----------|-------|
+| **Jewel case (external)** | 142 × 125 × 10 mm | 5.59" × 4.92" × 0.39" | ±0.5mm tolerance |
+| **Front insert (visible)** | 120 × 120 mm | 4.724" × 4.724" | With 3mm bleed: 126 × 126 mm canvas |
+| **Back insert (tray paper)** | 151 × 118 mm | 5.94" × 4.65" | Includes folded spines on both sides (~15mm each) |
+| **CD disc** | Ø 120 mm | Ø 4.724" | Standard CD diameter |
+| **CD center hole** | Ø 15 mm | Ø 0.59" | Spindle hole |
+| **CD disc thickness** | 1.2 mm | 0.047" | |
+| **Spine width (single)** | ~7 mm | ~0.28" | For a single CD jewel case |
+| **Jewel case open width** | 284 mm | 11.18" | Two facing panels + spine gap |
+
+### Web Scaling Analysis
+
+The README uses **2× scale** (142mm → 280px, 125mm → 245px). At 96 DPI standard web resolution:
+- 1mm ≈ 3.78px
+- So 142mm × 3.78 ≈ 537px would be exact 1:1 scale
+- 2× of 142mm = 284px, which is a **0.53× scale** at 96 DPI
+- The rationale: 280×245px is a compact, usable web component size that preserves the aspect ratio
+
+**Recommendation:** The 2× multiplier is fine for the default scale, but implement `--cd-scale` as a multiplier variable (default: 1 for 2× web scale). This lets users adjust without recalculating every dimension.
+
+Formula:
+```css
+--cd-scale: 1; /* 1 = 2× of physical mm → px */
+--cd-jewel-width: calc(142px * var(--cd-scale));
+--cd-jewel-height: calc(125px * var(--cd-scale));
+--cd-disc-diameter: calc(120px * var(--cd-scale));
+--cd-leaflet-size: calc(120px * var(--cd-scale));
+--cd-spine-width: calc(7px * var(--cd-scale));
+```
+
+### Region Variations
+
+| Standard | Body | Notes |
+|----------|------|-------|
+| ISO 15727:1998 | Global | Original jewel case standard |
+| IEC 60908 | Global | CD-DA (Red Book) physical spec |
+| Regional | None significant | Jewel case dimensions are globally standardized — CDs fit worldwide |
+
+No significant regional variations. The 142×125×10mm form factor is universal.
+
+### Tray Paper & Leaflet Physical Layout
+
+The back tray paper (151×118mm) folds into three panels:
+- **Left spine:** ~7mm (visible from front/back)
+- **Center:** 120×118mm (back insert surface)
+- **Right spine:** ~7mm + 7mm fold at edge
+
+The leaflet/booklet is usually:
+- **Single sheet:** 240×120mm folded in half → two 120×120mm pages
+- **Multi-page:** 480×120mm folded into 4 panels of 120×120mm each
+- **Stapled booklet:** 120×120mm pages bound at center fold

+## Q3: ASW Design Patterns (`~/releases/asw/`)
+
+### Architecture Overview
+
+ASW (Agentic Semantic Web) is a zero-class CSS framework built on Open Props. Source verified at `~/releases/asw/src/`.
+
+**Layer order (11 layers):**
+
+| # | File | Purpose |
+|---|------|---------|
+| 00 | `00-reset.css` | Box-sizing, margin reset |
+| 01 | `01-tokens.css` | Semantic aliases on Open Props (~300 tokens) |
+| 02 | `02-typography.css` | Heading, body, code, table, link styles |
+| 03 | `03-landmarks.css` | `body > nav`, `article`, `section`, `footer`, `hgroup`, `dt/dd` |

+### Key Semantic HTML Patterns
+
+**Navigation:**
+```html
+<body>
+  <nav>
+    <strong>Brand</strong>
+    <ul>
+      <li><a href="/" aria-current="page">Home</a></li>
+      <li><a href="/about">About</a></li>
+    </ul>
+  </nav>
+```
+
+**Articles with container queries:**
+```html
+<article>
+  <header>
+    <h3>Title</h3>
+  </header>
+  <p>Content adapts to parent width via container queries.</p>
+</article>
+```
+
+### Data-Attribute Vocabulary (for OpenCD consideration)
+
+| Attribute | Purpose |
+|-----------|---------|
+| `data-role` | Command-box, timeline, status-card, diff, log-entry |
+| `data-wikilink` | Wiki-style internal links `[[Note Name]]` |
+| `data-task` | Task list states: todo / done / blocked |
+| `data-status` | Status indicators: awake / sleeping / blocked |
+| `data-callout` | Callout boxes: note / warning / error / tip |
+| `data-session` | Session metadata display |
+| `data-tag` | Tag display with # prefix |
+| `data-tooltip` | CSS-only tooltips (no JS) |
+| `data-subnav` | Sub-navigation with / separators |
+| `data-diff` | Diff viewer with +/- lines |
+| `data-redacted` | Privacy redaction (bar / reveal / label variants) |
+| `data-theme` | Light/dark theme toggle |
+| `data-nav-links` | Nav link container for Flexbox push-right |
+| `data-nav-toggle` | Mobile hamburger toggle |
+
+### Token System (ASW → Open Props Mapping)
+
+ASW's token layer (`01-tokens.css`) uses Open Props as a foundation and adds:
+- **Surface tokens:** `--surface`, `--surface-1`, `--surface-2`, `--surface-3`, `--surface-card`, `--surface-hover` — all `oklch()` with `--palette-hue` tinting
+- **Text tokens:** `--text`, `--text-2`, `--text-3`, `--text-dim`
+- **Accent tokens:** `--accent`, `--accent-hover`, `--on-accent`, `--accent-subtle`
+- **Fixed-hue accents:** `--accent-blue` (250°), `--accent-red` (25°), `--accent-orange` (80°)
+- **State colors:** `--ok` (green 145°), `--warn` (amber 80°), `--error` (red 25°), `--info` (blue 250°)
+- **Gap fills:** `--space-3` (0.75rem), `--space-5a` (1.25rem) — values missing from Open Props
+- **Text scale gap:** `--text-sm` (0.875rem) — missing from Open Props (`--font-size-0` is 0.75rem, `--font-size-1` is 1rem)
+- **Radius gap:** `--radius-md` (4px) — between OP `--radius-1` (2px) and `--radius-2` (5px)
+- **Layout widths:** `--width-sm` (510px) through `--width-2xl` (1450px)
+- **Content widths:** `--width-prose` (65ch), `--width-report` (72ch)
+- **Fonts:** `--font-heading` = `var(--font-neo-grotesque)`, `--font-ui` = `var(--font-neo-grotesque)`
+
+**Key insight for OpenCD:** The ASW approach of using Open Props for the backbone + semantic aliases for the project-specific tokens is exactly the right pattern. OpenCD should define `--cd-*` tokens as semantic aliases on top of Open Props, with fallback values.

+## Q4: CD Packaging Design References
+
+### Parental Advisory Label (Source for Human Advisory Badge)
+
+**Verified from:** Wikimedia Commons SVG + Wikipedia
+
+| Specification | Value |
+|---------------|-------|
+| **Aspect ratio** | 523×327px ≈ 1.6:1 |
+| **Typography** | Impact / Arial Black (heavy sans-serif, tightly tracked) |
+| **Layout** | 3 rows: "PARENTAL ADVISORY" / "EXPLICIT CONTENT" (on black), white text, all-caps |
+| **Designer** | Deborah Norcross (Warner Bros) — 1990 |
+| **Current text** | "PARENTAL ADVISORY: EXPLICIT CONTENT" (since 1996) |
+| **Construction** | Two black bars (top 40%, bottom 40%), white text centered |
+
+### Human Advisory Badge (Local Implementation)
+
+**Files at:** `~/releases/human-advisory/` and `~/releases/parental-advisory/`
+
+The existing `.human-advisory` implementation uses:
+- Container: `300px × var(--ha-size)` wide, `border: 3px solid #000`, `background: #000`
+- Font: `Impact, 'Arial Black', 'Helvetica Neue', sans-serif`
+- Three rows: "HUMAN" (white on black), "ADVISORY" (black on white), "EXPLICIT AI CODE" (white on black)
+- Scalable via `--ha-size` CSS custom property
+
+**For OpenCD's `.human-advisory` module:** The DESIGN.md already specifies `--cd-advisory-red` from `--red-6`, which is the correct approach. Consider supporting both:
+- Classic PA-style: black/white bars
+- OpenCD variant: red/black with white text
+
+### Visible Grid Aesthetic — Key References
+
+**1. trentuna.com paper-card grid:**
+```css
+.paper-card {
+  background-image: repeating-linear-gradient(
+    0deg,
+    transparent 0 31px,
+    oklch(40% .02 55/.025) 31px 32px
+  ), var(--grain);
+}
+```
+Uses 31px spacing between horizontal lines, 1px rule. Very subtle.
+
+**2. CD tray paper (physical):**
+- Typical grid: fine dots or thin parallel lines at ~1mm spacing (≈4px at web scale with grid repeat)
+- Texture: matte-finish paper, slight grain
+- Color: silver/gray or clear translucent
+
+**3. Recommended grid for OpenCD:**
+```css
+/* Default: fine horizontal lines (tray paper aesthetic) */
+--cd-grid-color: var(--gray-3);
+--cd-grid-size: 8px; /* line interval */
+background-image: repeating-linear-gradient(
+  0deg,
+  transparent 0 calc(var(--cd-grid-size) * 1 - 1px),
+  var(--cd-grid-color) calc(var(--cd-grid-size) * 1 - 1px) var(--cd-grid-size)
+);
+```
+
+### 5 Distinctive CD Packaging Examples (for Visual Direction)
+
+1. **Aphex Twin — Selected Ambient Works 85-92** (R&S): Minimal jewel case, black on white, solid sans-serif typography. The CD itself has a subtle reflective design.
+2. **Boards of Canada — Music Has The Right To Children** (Warp/Wax): Dark jewel case with visible disc through transparent front, minimal tracklist layout on back.
+3. **Radiohead — Kid A** (Parlophone): Special edition with clear plastic case, hidden booklet art, minimalist typography.
+4. **Depeche Mode — Violator** (Mute): Iconic red rose on black. Simple, bold, high contrast.
+5. **The Postal Service — Give Up** (Sub Pop): Transparent jewel case, dual-layer art (front insert + back tray paper visible through clear case).

+**Url:** https://trentuna.com — Live catalog page  
+**Stylesheet verified:** Custom Tailwind CSS v4 build, warm vintage aesthetic
+
+### Typefaces
+| Role | Font | Stack |
+|------|------|-------|
+| **Display / Headings** | Fraunces | `"Fraunces", "EB Garamond", Georgia, serif` |
+| **Body** | EB Garamond | `"EB Garamond", "Iowan Old Style", Georgia, serif` |
+| **Monospace** | JetBrains Mono | `"JetBrains Mono", "IBM Plex Mono", ui-monospace, monospace` |
+
+### Color Palette (Oklch)
+
+| Token | Value | Purpose |
+|-------|-------|---------|
+| `--paper` | oklch(95.5% .018 85) | Warm cream background |
+| `--paper-deep` | oklch(92% .025 80) | Slightly darker paper |
+| `--ink` | oklch(18% .015 50) | Dark warm text |
+| `--ink-soft` | oklch(36% .018 55) | Secondary text |
+| `--ink-faint` | oklch(55% .02 60) | Subtle text |
+| `--rule` | oklch(32% .02 55) | Border/rule color |
+| `--accent` | oklch(55% .18 32) | Warm red accent |
+| `--stamp` | oklch(45% .16 28) | Darker stamp color |
+
+### Grid Approach
+
+trentuna.com uses a **visible paper-lined grid** — the structure IS the decoration:
+- `repeating-linear-gradient(0deg, transparent 0 31px, rule-color 31px 32px)` for horizontal notebook lines
+- `radial-gradient` grain texture (8 layers, varying dot sizes from 7px to 31px)
+- `radial-gradient` vignette effect
+
+This directly inspires OpenCD's CD tray paper grid.
+
+### Content Structure (from live page)
+```
+trentuna / catalog
+TNT-000 · MMXXV
+"IMPRINT FOR OPEN AI SYSTEMS"
+"We release software, notes, traces, and unfinished but useful machinery."
+[Human Advisory — Explicit AI Code badge]
+```
+
+### Key Lessons for OpenCD
+
+1. **Warm paper tones** work for backgrounds — consider `--cd-tray-bg` with slight warm tint
+2. **Serif body + sans navigation** is a readable combination
+3. **Visible grid-as-decoration** creates tactile feel with minimal CSS
+4. **Monospace for metadata** (catalog numbers, labels, timestamps)
+5. **Bold accent color** for interactive elements (the red accent against warm paper)
+6. **Grain texture** adds depth without images
+

+
+## Cross-Reference: DIRECT.md Mapping Corrections
+
+### What's Right
+- Most Open Props token mappings are correct
+- CD physical dimensions are accurate (ISO 15727)
+- The 2× scale is a reasonable default
+
+### What Needs Corrections
+1. **`--surface-1` through `--surface-4` are NOT Open Props out-of-the-box.** They need to be defined as custom variables. The DESIGN.md already does this correctly (`--cd-tray-bg: var(--surface-1)`) but assumes `--surface-1` exists from Open Props. **Define them explicitly** in `_variables.css`.
+
+2. **`--grid-*` tokens don't exist in Open Props.** The `--grid-1`/`--grid-2` references in DESIGN.md need to be custom `--cd-grid-color` / `--cd-grid-color-alt` definitions using gray-3/gray-2 shades from Open Props.
+
+3. **ASW's `--space-3` (0.75rem)** and **`--text-sm` (0.875rem)** fill gaps in Open Props that OpenCD should also define if needed.
+
+4. **Font selection:** The DESIGN.md uses `var(--font-sans)` for CD spine labels. Consider `var(--font-neo-grotesque)` which has a cleaner, more label-appropriate appearance (Inter/Roboto).
+

+
+## Intelligence Summary
+
+| Area | Confidence | Risk | Notes |
+|------|-----------|------|-------|
+| Open Props tokens | ✅ Verified | Low | All source-confirmed |
+| CD dimensions | ✅ Verified (ISO) | Low | Global standard, no region variance |
+| ASW patterns | ✅ Local source | Low | Full source access at ~/releases/asw/ |
+| Human Advisory | ✅ Local source | Low | Working implementation exists |
+| trentuna.com | ✅ Live site + stylesheet | Low | Tailwind v4 custom build, warm paper aesthetic |
+| Surface/Grid tokens | ⚠️ Correction needed | Medium | DESIGN.md assumes OP has surface/grid tokens |
+| CD scale factor | ⚠️ Recommendation | Low | Implement --cd-scale; keep 2× as default=1 |
+
+**Bottom line:** Green light for implementation. Surface and grid tokens need custom definitions (noted above), everything else maps correctly. The ASW token pattern (oklch with palette-hue) is a proven approach that OpenCD should adopt for its CD tray paper colors.
