/* Hallmark · pre-emit critique: P5 H4 E5 S5 R5 V5
 * macrostructure: Docs Detail · genre: atmospheric
 * theme: Marquee (locked by design.md) · mode: dark-primary (light toggle)
 * Per-skill static reference page — typography + hairlines only, no billboard,
 * no rails (a reference page, not a browsing surface).
 * Reuses the same component language as the catalog's detail overlay
 * (.detail-header / .detail-tabs / .detail-section / .install-block / .skillmd-viewer)
 * so the static page and the in-catalog overlay read as one component, not two.
 * Imports tokens.css + base.css (unmodified) — adds only page-specific rules.
