bridge pages: SEO/GEO audit fixes (titles with live leader, false claims removed, internal links, stale hub columns)

[Flotapponnier]

Follow-up to the bridge SEO/GEO audit (.saudit/bridges/report.md, verdict FIX THEN SHIP).

Blockers

• bridge-fee / bridge-quote-latency: seo_title and seo_description now carry the live leader and number (Cheapest USDC bridge: Squid Router at 0.0067% all in, Fastest bridge quote API: Mobula at 40 ms (live p50)), descriptions 148/150 chars with the trailer named. 367 impressions, 1 click behind the old generic titles.
• False measured claims removed from FAQ/findings (all in FAQPage JSON-LD): "vary 10x" (live spread 164x), "$5, $50, $300, $1000 and $10000 buckets" (harness quotes 5/50/300), "100 to 400 ms", "5x gap… 10 to 20x", "on the roadmap" corridor breakdown (the tabs exist), 10-bucket histogram list (16 buckets since 2026-09-19).
• Answers: which-bridge-has-the-cheapest-usdc-fee answers in the first sentence with {{best_name}}/{{best_p50}} instead of a URL and a typed cohort of six; cheapest-bridge-usdc-to-base rewritten on the real corridor (Sol to Base cell via {{best_name:chain:Base}}, bridge_cost_percent, 24h p50; it claimed Ethereum to Base, bps, 24h average, per-size tabs); which-bridge-has-the-fastest-quote-api drops the typed list, the three-regions claim and discloses NI's fixed 3 s wait; duplicate meta description gone; answers seo_title now renders placeholders.
• Validator: placeholder resolution now runs on answers/*.yml against their bench, plus a rule against {{count}} <noun> (A, B, C, D…) typed cohorts. It caught what-is-the-highest-crypto-staking-yield (Sui listed, 6 measured), fixed too.

Majors

• Internal linking: AnswersForBench on bench pages and the /bridge hub; CompareThisBench on answers pages and the hub.
• /bridge hub: title/description rewritten, "three regions" gone, as-of line, em dash removed. Also a real data bug: the US/SGP columns showed 2026-09-09 figures (stale KV variants no longer materialized since the region dimension was scoped to EU-West). Variants older than the stale threshold are ignored and the table renders only regions with live data.
• /products/<slug> meta: short bench labels for non-RPC benches (title head, or <category noun> <metric> when long).
• /compare/<a>-vs-<b>: FAQ questions deduped (bench named when both winners share the verb), description date from the newest shared run instead of new Date(), title X vs Y 2026: N live benchmarks compared.

Minors

• Ad hoc compare pairs above the live floor enter the sitemap (91 on dev, incl. lifi-vs-relay which ranks at 4.0); lastmod from the shared benches' specs.
• Registry-only product pages take the registry file's lastmod instead of catalogTs; benchmarks/compare/products [slug]/page.tsx in the git-mtime manifest.
• Answers pages ship the Highwire citation_* block.
• Bridge report front matter: title without "Best", 151-char summary, dated hero finding.

Verified locally on a fresh dev server: titles, descriptions (all ≤158), FAQ uniqueness, 0 leftover {{, links counts, sitemap sections; pnpm validate, tsc (src clean), 272 tests pass.
