/* dmari.de - Text index: variant A tile grid (quiet grid, 3/2/1 columns). 2026-09-28.
   Loaded only by text.html (body.text-tiles), after /css/styles.css and /css/text-filter.css; uses their tokens only
   (--ink, --mute, --faint, --line, --font-ui, --bg). Shared CSS/JS unchanged.
   Layout math for the img sizes attribute in text.html: .text-index = min(100%, 72rem) with 1.25rem side padding,
   list max 68rem (1088px); 3 cols >1080px (gap 2.25rem) -> max tile 338.67px; 2 cols 641-1080px (gap 1.75rem)
   -> (100vw - 68px) / 2; 1 col <=640px -> 100vw - 40px. Keep sizes in sync if gaps/breakpoints change. */
