   ============================================================
   Support tab v2 — editorial visual language for the
   member-facing Support tab. All rules scoped to .sup-page-v2
   so this file cannot bleed into other tabs.

   Promoted from mockups/_mockup-support.css on 2026-05-15
   (Phase 2 of the Support redesign). Companion to
   oecta-tokens.css + oecta-components.css. Implements the
   rules in mockups/SUPPORT-DESIGN.md.

   Visual chain: shell renders .portal-hero-compact above
   #tab-assist-content; everything inside this file lives
   below that, within the .sup-page-v2 block.
