/* ===================== dark mode (system theme, no toggle) =====================
   The site follows the OS appearance via `prefers-color-scheme` — there is no
   in-page switch. When the system is dark these overrides apply automatically.
   Most surfaces (cards, footer, units, value/step cards, headings) already read
   from the --bg / --ink / --muted / --card variables, so simply re-pointing
   those recolours the whole page for free. The selector rules below only restate
   the handful of places that hard-coded a light-mode colour: the near-black
   monochrome glyphs, the dark download pill, the fixed grey body prose, and the
   roadmap bullets. Dark screenshots are swapped in the markup via
   <picture> + a `(prefers-color-scheme: dark)` <source> (img/dark/*). */
