/* ----------------------------------------------------------------------------
   Dark/obsidian gate — this file is pure hardcoded hex (no CSS custom
   properties), so none of tetra-kairos-skin.css's --panel/--muted token
   redefinitions give it a free ride. tetra-theme-system.css still forces
   h1-h4/p text light under any [data-tetra-theme], so the now-light heading
   text goes near-invisible against a surface that stays white/near-white.
   Same glass treatment as the shared library hub-family fix in
   tetra-kairos-skin.css. Every selector below is gated to dark/obsidian;
   light mode is untouched.
