   RIA — LANDING CONTENT LAYER
   Brings the long-form content from /methodology, /about, and /support
   onto the landing page in editorial-format sections. Consumed after
   landing-editorial.css + landing-3d.css + landing-cinematic.css.

   Sections (top to bottom on landing):
     • .ria-manifesto      — mission / activism / quote
     • .ria-method-grid    — 4-step detection pipeline cards
     • .ria-commitment-row — Ethical AI · Open Source · Public Good
     • .ria-support-block  — donate + open-source CTA
     • .ria-stat-row       — key facts that hit hard
