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.
