0.9.0 — shared check code

Three new exports. The three sites re-pin and delete their copies next.

• ./verify/design — 472 lines that were byte-identical in all three sites.
• ./verify/http — httpStatus, which reads and discards the response body. Node 22's undici asserts assert(!this.paused) when a socket ends with an unread body; that crashed 6 of 12 CI runs before this helper existed.
• ./verify/pages — pageChecks({ SITE, BASE }), the nineteen shared check bodies. A factory because seo and card close over those two names, which lets all nineteen bodies move unchanged.

All nineteen were compared against the sites' text with their preceding comments, mechanically; the only accepted differences are a uniform two-space indent shift and two orphaned prefaces belonging to neighbouring functions.

Tests 120 → 131, every one mutated and seen red before being trusted. Zero dependencies, zero devDependencies, no Playwright import.
