/* ==========================================================================
   FlowGuard interface.

   Colour comes from the theme layer (ThemeService emits --fg-surface-*,
   --fg-ink-*, --fg-accent-*, --fg-state-* and the density variables). Anything
   that is NOT theme-dependent — the type scale, spacing rhythm, radii and
   elevation — is defined here, because a customer changing palette should not
   be able to change the spacing rhythm of the product.

   The decision-state colours (allow / monitor / challenge / rate-limit / block)
   are identical in every palette by design. If "blocked" were teal for one
   person and amber for another, the colour would stop carrying meaning, and
   reading state at a glance is this interface's whole job.
