/* ---------- dark mode ----------
   Screenshots are captured from the app's dark theme, so a dark page is the
   more honest reading surface — the figures stop being bright rectangles on
   white. Colour lives entirely in the custom properties above, so this block
   only re-points them; no component rule is duplicated.

   `[data-theme]` is set by an inline script in <head> BEFORE first paint, so
   there is no white flash for a reader who chose dark. */
