/* ============================================================================
   BookedCentral — marketing site styles  (Design Specification v1.1)
   ----------------------------------------------------------------------------
   Reads ONLY the semantic tokens in tokens.css — no literal colours or fonts
   here, so the final design assets plug in via tokens.css alone. The site IS
   the product's design language at rest (§8.3): same tokens, no separate
   marketing theme.

   The four identity moves are threaded through, not decorated on top:
     · Signal Copper appears ONLY where the machine is speaking (§2.1.1)
     · tick-and-rule scaffold instead of cards-on-shadows (§2.7.2)
     · the fixed 63:37 split on two-pane bands (§2.7.1)
     · tracked-mono eyebrow paired directly above a serif headline (§2.2.1)
