/* ============================================================================
   annaconda — shared design system
   ----------------------------------------------------------------------------
   One stylesheet for every page, so the identity is set once and cannot drift.

   The thesis, in the type: everything TRUE in this system is fixed-width —
   a SHA-256 seal, a T1055.012 technique id, a 5569/10000 score, a verdict
   state. So the monospace is the hero (the EVIDENCE), the sans structures the
   chrome, and a single serif line carries the human CLAIM. Colour is earned by
   meaning: the only chroma is the instrument teal (chrome, integrity) and the
   four verdict states (malice, escalate, abstain, benign). Sealing is teal,
   never red — red means malice and nothing else.

   Signature element: the hash chain drawn as a visible connected spine
   (.spine), so the tamper-evident record is a physical object on the page and
   an unbroken line reads as a passing verification.
