   shakedewan.com — record design system
   --------------------------------------------------------------------------
   Promoted from /next/record/ on 2026-09-02. Prefix .rc.

   Colour works by variable remapping, not by per-component overrides: the
   root .rc sets --bg/--fg/--fg-2/--line/--accent, and .rc-sec--paper simply
   reassigns those five. Every component below reads the variables, so an
   inverted section needs no special-case rules and cannot fall out of sync.

   Self-contained. Pages using this do not link light.css, so the previous
   light design and this one cannot bleed into each other.
