/* strop.dev — house style (plan 0003 §5): one accent color, desaturated
   base, warm text, clean Unicode, zero animation theater (the caret is
   the editor's heartbeat — allowed, plan 0004 §2).

   Palettes: :root carries the default "strop" palette; each
   [data-palette] block overrides the full var set. The logo SVG is
   inlined in index.html and painted entirely from these vars, so it
   re-themes live with the page (rootle does this swap at build time;
   the placeholder site has no build step, so vars do it client-side). */
