/* ==========================================================================
   La Galería — Public stylesheet (index.php, artists.php, artist.php,
   gallery.php, artwork.php)

   Minimal high-end gallery theme: white background, black type, a single
   muted neutral for secondary text. Deliberately separate from the main
   cdlav.org site's dark "smoked glass" / teal-mustard-terracotta look — La
   Galería is its own identity now. Plain CSS, no preprocessor, no framework.
   Load once via header_public.php.

   This is NOT the admin theme (gallery-admin.css is a separate file).

/* ---- Dark theme (?theme=dark, set via header_public.php's $theme /
   data-theme attribute — see gallery_theme_toggle_href()). Not a naive
   invert: near-black instead of pure #000 (less harsh, keeps shadow detail
   in artwork photos), soft off-white instead of pure #fff (avoids halation).
   Contrast checked against WCAG AA (4.5:1 for normal text):
     --color-fg #f2f2f2 on --color-bg #121212   -> ~16.7:1
     --color-muted #a3a3a3 on --color-bg #121212 -> ~7.4:1
     #d4d4d4 (bio/stat body text) on #121212     -> ~11.8:1
   Every component below (.btn-nav, .lang-toggle, .filter-chip, .empty-state,
   .artwork-image-area, etc.) already reads color through these custom
   properties, so overriding just the tokens re-themes the whole page —
   including the invert-on-hover/active interactions, which flip to solid
   white-on-dark automatically since they're built from var(--color-fg)/
   var(--color-bg) rather than hardcoded black/white. The lightbox
   (rgba(0,0,0,0.92) scrim + white close button) is intentionally NOT
   touched here — a dark viewing scrim is correct in both page themes. */
