/* ====================================================================
   The Body Clock Audit - quiz
   Hand-coded. No framework, no webfonts, no external dependencies.
   Everything scoped under .cca- so Astra cannot collide.

   CONTRAST NOTE: the brief sets a non-negotiable 7:1 minimum.
   --cca-amber (#C98A3F) cannot carry body text at that ratio on any
   ground in this palette (best case ~5.97:1 against midnight), so amber
   is used for non-text accents only - progress fill, selected marker,
   button edge. Text that needs to read as "amber" uses --cca-signal,
   which is 10.5:1 on midnight. See handover notes.
