/* ═══════════════════════════════════════════════════════════════
   AIMT Education Library — editorial page primitives
   ---------------------------------------------------------------
   Standalone, additive stylesheet for /education/* pages. Reuses
   assets/css/aimt-design-system.css tokens and the shared
   .aimt-legal-* / .aimt-sp-* primitives from
   assets/css/aimt-supporting-pages.css rather than inventing a new
   visual language -- this file only adds the handful of
   education-specific compositions (hero, evidence indicator, scope
   callout, takeaways, sources, related) that those files don't
   already cover.

   Depends on aimt-design-system.css + aimt-supporting-pages.css
   (load both first).

/* ---------- Editorial heading system (Owner Correction Pass) ----------
   Scoped to this Education stylesheet only -- does not touch the shared
   Tier 2 Playfair Display h1/h2 tokens that about/research-standards.html,
   terms.html, privacy.html, refunds.html, and verify.html still use.
   Structured Montserrat instead of the editorial serif, kept refined
   (moderate weight, tight-but-not-heavy tracking) rather than the bold
   uppercase Tier 1 marketing treatment. Body copy stays Outfit
   (--aimt-font-sans); eyebrow/micro-label/evidence-system text stays
   mono (--aimt-font-mono) -- see .aimt-edu-scope h2 below, which is
   deliberately in that micro-label bucket, not this heading system. */
