/* ============================================================================
   Ferry console — one stylesheet, no build step, no external assets.

   Aesthetic: an instrument panel that prints like a compliance report.
   Editorial serif for headings, system sans for interface, monospace with
   tabular figures for every number — because in this product the numbers are
   the argument. Hairline rules instead of shadows and cards.

   Colour: chart marks use the validated categorical palette (--series-*) and
   the reserved status palette (--st-*). Chrome uses --accent, a cyan that
   appears in no plot, so interface colour can never impersonate a series.
