/* "Four materials, one weak spot" (what-are-full-arch-implant-teeth-made-of, #nanoceramic): owner-approved and locked 2026-10-29 (Daniel:
   "approved- send to lead to give to claude for publish"; Codex materials v002, final list). Site placement of the locked style.css: every rule
   scoped to .dio-materials, values unchanged; the h1/h2 rules style the widget's h3/h4; the page shell, controls, button rules and @font-face are
   dropped (the site's fonts.css supplies Nunito Sans); the 600/350 media queries are container queries on the widget; the arch mask is the site's
   own assets/arch-tile.svg, resolved from this stylesheet's folder. */
