/* Next Pattern — the site's own stylesheet. kit.css (loaded first) holds the
   shared design and every token; this file sets only the accent and what a
   public, long-form reading site needs that the kit lacks. Same pattern as
   plate-and-glass's app.css.

   ACCENT: deep green. Checked by hand against the kit's backgrounds:
   light  white on --accent 6.3:1; --accent-strong on --bg 8.4:1, on
          --surface-sunken 7.8:1; --accent on --bg 5.9:1.
   dark   white on --accent 5.2:1; --accent-strong on --bg 9.1:1, on
          --surface 8.2:1. As in plate-and-glass, dark mode keeps the same
          structure as light (white on a deep fill) and --accent-strong is the
          bright tint used for text and edges. */

   One idea: a Truchet-tile pattern in the accent, very faint, behind a large
   wordmark. Contrast: --text on --bg 13:1 light / 14:1 dark; --text-muted on
   --bg 4.9:1 light, 8:1 dark (the pattern sits at <=0.2 opacity under a mask
   that thins it behind the text, so text contrast is not materially reduced);
   the note uses --accent-strong, 8.4:1 / 9.1:1. */
