/* ==========================================================================
   UNIFIED COMPONENTS
   One set of markup, two design treatments. This file contains no colour
   literals and no font names — everything visual comes from theme.css.

   How to read this file
   ---------------------
   Each component is written once as its shared structure, then followed by
   the small number of rules that differ between themes, marked:

       /% LIGHT %/   rules that apply when data-theme is absent or "light"
       /% DARK  %/   rules that apply when data-theme is "dark"

   Light is the default, so light rules are unprefixed and dark rules are
   scoped to [data-theme="dark"]. That keeps the no-JavaScript fallback on a
   complete, coherent design rather than a half-themed page.
