   technology-composition.css — v0.3
   ─────────────────────────────────────────────────────────────────────
   Composition-seam rules for /technology v0.3. Two jobs:

   (1) Section register and prose helpers (.r3-*) used by §3b / §3c /
       §4b / §4c prose blocks and the §3 act-opener UMBRELLA strip —
       page-level scaffolding, not component-internal styling, so they
       belong here rather than in any single component file.

   (2) §6 closing band (.ws-tech-closing) — page-local component for
       /technology only, ported from v0.2.

   All values use webshield-navy.css tokens. No raw hex / rgba.
   No new tokens introduced.
