/* =============================================================================
   Login consent / legal-gate screen — templates/consent.html
   -----------------------------------------------------------------------
   2026-07-24: the gate went live (CONSENT_GATE_ENABLED_ORG_IDS=*) and the
   screen rendered in generic light styling — jarring, because it looked
   nothing like the app the user was already in. This sheet rebuilds it on
   the SAME theme tokens the rest of Claimind uses (static/styles.css
   :root + body[data-theme="pro"|"slate"|"dark"]), so the gate inherits
   whatever theme the user picked instead of ambushing them with white.

   HEX-FREE BY CONTRACT. Every color here is a var(--…) token so all three
   themes track automatically; tests/test_consent_page_theming.py pins it.
   (`rgba(0,0,0,…)` shadow washes are the one allowed literal, matching the
   convention in tests/test_theme_content_recolor_contract.py.)

   Loaded from templates/consent.html's `head_extra` block AFTER
   static/styles.css, which is what lets `body.auth-body.consent-body`
   below beat styles.css's hardcoded `body.auth-body { background: … }`.

   unreachable (the classic flex-centering overflow trap). flex-start + page
   scroll keeps the whole card reachable at every height. */
