🔎 Discovery on-site gaps — the touchable half of 16/41

Probe-verified before coding: density 4.47% (bar 5%), "Yonyon" appeared ZERO times as text on the site, Wikidata entity existed but the checker searched the apex brand.

before: 5,306 / 118,610        = 4.47% ❌
added : ~+1,100 SSR text chars (What-is section + footer + hub links on home)
after : ~6,400 / ~120,000      ≈ 5.3% ✅ (verified against the production build)

Deliberately NOT done here: Wikipedia article (notability needs press first — premature = deletion + salted title), hidden-text stuffing (cloaking), share-of-voice content batch + launch-kit drafts (separate PR; human posting gates apply).
