rails: build from tags via shared rail-match helper (fix degenerate single-rail collapse)

e16b18cc7b1596c12f858e7987dd02fe9c9ffaa9 · 2026-05-26 10:18:00 -0700 · Steve Abrams

- Add require('../_shared/rail-match') for buildRails/railFacets
- /api/sliders: use buildRails(PRODUCTS_NICHE, SITE_RAILS) — tags-aware, multi-membership
- /api/facets aesthetics: use railFacets() — consistent with sliders
- site.config.json rails[]: replace aesthetic-only buckets (silver/antique/chrome) with
  tag-frequency-driven buckets: contemporary(62%), vinyl(60%), gray(59%), geometric(26%),
  textured(59%), modern(25%) — all clear 8% threshold, none vendor names
