/* "Tooth and implant, when the gum gets inflamed" (periodontitis versus peri-implantitis), owner-approved v008 2026-10-30
   (Daniel: "ok good to go- send it to claude..."; Codex approved-delivery-v008, DELIVERY-MANIFEST.json, OWNER-APPROVAL.json).
   Site placement of the locked style.css: every rule scoped to .dio-peri-comparison, values unchanged. Dropped: @font-face (the site's
   fonts.css serves Nunito Sans), the page shell (:root/body/main) and the global reset; --dio-brand-navy and the Avenir Next stack sit on
   the widget root instead of :root. h1/h2/h3 are shown as h3/h4/h5. The arch field masks with the site's own assets/arch-tile.svg (same
   file, same hash as the lock's copy). The button finish is the site's button-finish.css (byte-identical to the lock's copy), already
   loaded on answer pages. The locked max-width:600px rules follow the component's width (container query), not the screen, because the
   widget sits in the answer header box. The IDs became per-instance classes (pc-play etc.). */
