/* ============================================================
   EXAM SPACES — components (ADR 0014)
   ------------------------------------------------------------
   Space switcher, per-space sidebar scoping and space choice
   screen, transposed from Pilote Militaire's dashboard.css
   (l.419-858) — same geometry, same states, same anatomy.

   The switcher lives ON THE INK RAIL, so it reads the on-ink
   accents (bright hue on navy), never the on-white ones: a navy
   ASTB-E accent on a navy sidebar would be invisible. The space
   choice screen is a light panel holding dark cards, exactly as
   PM's, so it also stays on the on-ink side.

   Each switcher option and each choice card carries its OWN
   space's tint: css/ff-tokens.css keys --track-* on
   .dash-space-option[data-space] and
   .dash-space-choice__card[data-space], so an option is tinted
   by the space it offers, not by the space that is active. The
   --accent-on-ink fallbacks cover the switcher toggle, which is
   keyed on .dash-space-switcher[data-space] instead.

   No raw hex here beyond the ink scrims: every colour comes from
   a token.
