/* =========================================================================
   methodology-page — page styles for /methodology. v0.1 (2026-05-27).
   Sources tokens from webshield-navy.css. Composes shared chrome and the
   compact-hero variant --portal (navigational register, matching /documents
   and /patents).

   /methodology is a long-form READING-PROTOCOL page (prose + one enumerated
   list), NOT a card index. Section scaffolding mirrors documents-page.css
   values (ws-meth- prefix, not shared) so the two pages stay visually
   consistent while remaining decoupled — same rationale as documents-page.css:
   a spacing change on one must not silently move the other.

   Page-specific vocabulary:
     • section scaffolding (.ws-meth-section* + eyebrow / title / intro)
     • body prose (.ws-meth-prose) — the long-form register /documents lacks
     • the sixteen-topic ledger list (.ws-meth-topics) — mono "NN / 16"
       ordinal rail, serif term, sans explanation; rhythm mirrors the
       universal-card rail (--ws-uc-rail-width / --ws-uc-col-gap).

   No cards here → universal-card.css is intentionally NOT loaded by this
   page. The "before you read" callout that links HERE lives on /documents
   and /investors (cross-reference-callout.css .ws-xref--card); this page
   does not carry one. See brief-methodology.md.
