   inner.css — Zhongli Weiye inner-page component layer
   -------------------------------------------------------------------------
   Owner: homepage-designer (DESIGN.md §3 global vocabulary, inner-page pass).
   The engine primer (style.css) is deliberately neutral: chrome, layout
   primitives and generic buttons live there; THIS sheet carries the
   content-vocabulary components that generated inner pages and the
   hand-written top pages are authored with.

   Design source: templates/zho-dual-realm/skin.css §2 tokens (same brand
   system: dark #0E1B2A / paper #F7F8FA / accent #1E5AA8 / action #F0B429).
   Duplicated as local custom properties here because inner pages do not
   link skin.css (homepage-scoped by rule R14 in DESIGN.md).

   Scope: linked by inner/top pages only (build_top_pages._ensure_inner_css
   auto-injects; common.render_page links it for generated pages).
   Motion: transform/opacity only; no animation without reduced-motion off.

/* =========================================================================
   W4a legacy-bridge completion (2026-09, homepage-designer)
   -------------------------------------------------------------------------
   contact-us.html / support.html carry the legacy content vocabulary
   (.faq__item / .field / .flow / .download / .contact-card ...) which the
   engine primer styles NEUTRALLY (placeholder --brand gray, off-brand reds).
   build_top_pages will force-link inner.css on ALL top pages; when it does,
   the rules below restate every legacy class on the DESIGN.md §2 token
   system so the pages are fully on-brand on first paint.

   Visual language is identical to the sibling zlb-* components, so the W2
   markup swap (faq__item -> zlb-faq__item etc.) stays seamless and these
   bridge rules retire cleanly. Scope guard: inner pages only — index.html
   never links this sheet (see W1 scope contract above).

   Warning ink: no danger token exists in DESIGN.md §2, so error/required
   marks use the badge--opt amber-dark #7A5A0E already shipped in this sheet
   (6.4:1 on light grounds, action-derived). Flagged for a --zho-danger
   ruling in the W4a report — single-point change if adjudicated.
