/* ==========================================================================
   quickImages — Design tokens
   Two named themes sharing one brand hue (coral / sunset coral):
     - Default (no class needed)  : "Coral Dusk"  — a dark, warm charcoal-brown
                                    backdrop with a vivid sunset-coral accent.
     - body.theme-light           : "Coral Bloom" — warm cream-white with a
                                    deeper burnt-coral ink for text/links.

   Every color used anywhere in this project MUST be one of the tokens below.
   Never hard-code a hex value inside a component rule — see
   docs/UNIVERSAL_DESIGN_PLAYBOOK.md §3.

   Two-tier accent (same convention as every sibling site): --accent is the
   fill/border/icon coral, always paired with --accent-contrast-text on top.
   --accent-ink is what text/links use sitting directly on the page
   background — a brighter coral in "Coral Dusk" (≈7.4:1 on the dark page),
   a deep burnt-coral in "Coral Bloom" (≈5.5:1 on the warm white).

  /* Per-component. --card-bg/--modal-bg/--modal-hdr-bg/--input-border must be

     — a custom property's var() reference is substituted once, using the
     inheritance context AT ITS OWN DECLARING ELEMENT, and that resolved
     value (not a live reference) is what descendants inherit. Since only
     :root declares these aliases, they'd otherwise stay frozen at :root's
     dark values even under body.theme-light, no matter what --bg-surface
     etc. are overridden to below (found via a real light-theme screenshot
