/**
 * site-header.css — ONE canonical header across every surface (landing, auth,
 * learn, blog, app). Light + translucent, warm-paper palette with explicit colors
 * (never theme tokens, which flip in dark mode). No backdrop-filter on this
 * always-visible sticky bar (LM-11) — a high-alpha wash fakes the glass.
 * Loaded LAST so it wins over per-page header rules. 2026-06-21.
