/* docs-v5.css — v5 visual system for the mnemur component-docs pages.
   Shared by docs.html + docs-core/gateway/evals/loops/telemetry/mq/voice.

   This is the v5 chrome (dual-theme tokens, nav, header, footer, wordmark)
   shared with index-v5.html / docs-system.html, PLUS the docs two-column
   layout, sidebar/TOC, and content typography — rebuilt against the v5 tokens
   so the reference pages match docs-system on both light and dark themes.

   The FOUC pre-paint theme script + the dark/light toggle live inline on each
   page (as on index-v5 / docs-system). The doc CONTENT and the docs-search.js
   DOM hooks (.docs-menu, #docs-search, #docs-results, #docs-nav, a.sub, .sel,
   .active) are unchanged — this file only restyles them. */
