/* ── Dark ─────────────────────────────────────────────────────────────────
   Chosen, not inverted. Three things drove it:

   * The page is a very dark blue-grey rather than black, and the text a soft
     white rather than pure. Pure white on pure black smears for older eyes —
     the effect gets worse with age, and this app is for two people in their
     sixties reading it at 5am before a delivery run.
   * The top bar and primary buttons stay *dark* green. Lifting the brand to
     a pale green would put a glaring band across the top of every screen,
     which is the opposite of why anyone turns dark mode on.
   * --ok diverges from --brand here. They share a value in light mode by
     coincidence: one is a background, one is text on a dark green wash, and
     in dark mode those need to go opposite ways.

   The viewer has three states, not two. A bare `prefers-color-scheme` block
   would be overridden by nothing when someone picks light explicitly, so the
   media query is guarded and the explicit choice is repeated below. */
