/* =========================================================
   SITE LAYOUT
   ---------------------------------------------------------
   Structure only. Every color comes from a theme sheet in
   assets/styles/themes/, linked right after this one as
   <link id="themeLink">. site.js picks the theme by date
   (Retro Electric normally, a holiday theme in season).

   Keep literal colors out of this file: a hex or rgb()
   written here can't be changed by a theme, so it would
   show up in every one of them. Neutral black shadows and
   overlays are the exception.

   THEMES: each theme defines these on :root
     color-scheme          light or dark, for native controls
     --color-bg-start / --color-bg-end    page background gradient
     --color-surface-deep                 dark end of section panels
     --color-raised / --color-raised-deep modal and card panels
     --color-input-bg / --color-button-bg / --color-optgroup-bg
     --color-table-start / --color-table-end
     --color-th-start / --color-th-end / --color-th-hover
     --color-row-alt                      radio list alternate row
     --color-text / --color-text-muted
     --color-accent        primary (links, headings, active)
     --color-accent-hover  secondary (hover, now playing)
     --color-on-accent     text drawn on an accent fill
     --color-error
     --rgb-primary / --rgb-secondary      "r, g, b" for glows
     --rgb-tint            "r, g, b" tint of raised panels
     --rgb-text-muted / --rgb-bg-start / --rgb-bg-end

   Theme motion plays by default. Wrap any theme CSS
   animation in @media (prefers-reduced-motion:
   no-preference), the same rule site.js applies to the
   canvas effects in effects.js.
