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.

<h1>Design Notes</h1>
|
||||
<p>This booklet is a demonstration of the leaflet component — the insert booklet found inside a standard CD jewel case. Each page measures 120 × 120 mm (240px at 2× scale), matching the ISO 15727 standard for CD packaging.</p>

<h1>Architecture</h1>
|
||||
<p>OpenCD is built on Open Props — a design token framework by Adam Argyle. Every dimension, color, and spacing value maps to a custom property, with fallback values for standalone use. The framework includes:</p>
|
||||
<ul style="margin-left:1rem; color:var(--cd-text-secondary); line-height:1.6;">
|
||||
<li>CD dimension tokens at 2× scale</li>
|
||||
<li>Semantic color aliases on Open Props</li>
|
||||
<li>ASW-inspired surface layers</li>
|
||||
<li>Visible grid overlays (tray paper aesthetic)</li>
|
||||
</ul>

|
||||
<h1>Token System</h1>
|
||||
<p>The variable layer defines ~40 custom properties organized into semantic groups:</p>
