   ELEVATED CONTEXT — MARKETING DESIGN SYSTEM
   Governed by APP-017 (Frontend Design Governance), APP-018 (Marketing
   Communication), APP-016 (Identity Continuity).

   Authored identity source of truth:
     docs/product/design/ELEVATED-CONTEXT-FRONTEND-IDENTITY.md

   Identity: cool graphite neutrals + a SINGLE governed-teal accent.
   NOT a purple->blue SaaS gradient (APP-017 Rule 29). The only saturated
   brand-glow is a CONTAINED RADIAL glow scoped to the dark brand hero
   (identity spec §3.1 bounded exception) and never a full-bleed linear
   gradient. Type: humanist system-UI for prose, ui-monospace for evidence
   (Rule 28). 8px rhythm, 4px instrument radius, hairline grouping.
