/* ==========================================================================
   OTT CORE — the one shared stylesheet every OTT product imports.

   Source of truth: OTT-DESIGN-CONSTITUTION.md (v2) + OTT-SANS-TYPE-SYSTEM.md.
   Everything in this file is fixed ecosystem-wide. The ONLY thing a product
   defines for itself is --accent (and, if it uses the light-toggle shell,
   which of the two shell modes it picks — see the constitution §3.5).

   This supersedes vibe-system.css as the linked source: that file's heavy
   glassmorphism/glow treatment (backdrop-blur cards, large glow shadows on
   hover, pulse-heavy interactions) conflicts with the constitution's own
   anti-pattern list (§12 — "heavy drop shadows, saturated gradients
   everywhere... nothing screams"). It was never actually linked from a
   product's templates. Do not import both files in the same product.

   Usage: link this file FIRST, then the product's own stylesheet (which
   sets --accent and any product-specific components) after it.
