shared/render.js: scrub head-baked vendor from product titles (audit 2026-05-28 task#53 addendum). scrubTags closed the tag-chip leak; titles like 'Versace 4 Metallic Wallcovering' still leaked the vendor via card-title + data-title (→ quick-view modal title + aria-label) + productPage <h1>/<title>/og:title. Add scrubTitleLead() (denylist-driven leading-vendor stripper, mirrors stripLeadVendor in _shared/api-vendor-redact.js but on THIS file's VENDORS_DENYLIST so chip+title stay on one list) + displayTitle() helper used by both card() and productPage() so the two derivations stay identical. House-brand-led names preserved; empty/generic remainder falls back to 'Designer Wallcovering'. CANARY-verified on designermagnetics.com (526 products): /catalog + /product visible-text vendor hits 0 (was: Versace in card-title+data-title), 0 empty/mangled titles, house brand preserved 67x. NOT DEPLOYED — follow-up tick fans out deploy + fleet-wide rendered-DOM re-verify per drift-aware plan.
