/* ==========================================================================
   Biohack Therapeutics — full-screen age / research-use entry gate.
   Fonts referenced by name only (Belleza / Instrument Sans) — the theme is
   responsible for loading them, this file never enqueues them.

   Colour strategy: the theme's own :root custom properties (--bg, --text,
   --teal, in base.css, loaded on every front-end page) are exact matches
   for the pale-background/charcoal/teal design tokens, so those are reused
   directly rather than duplicated here. The theme has no equivalent for the
   muted-text or hairline tokens — base.css's --text-muted is a translucent
   rgba() over charcoal, not the flat #6B7A87 given, and --border is a
   different colour (#E1EEF0) entirely — so those two are declared locally,
   scoped to .bhc-gate the same way calculator.css scopes its own --bhc-*
   tokens to .bhc-calculator instead of :root.
