/* Ronde 3 (plan 124, stap 3): de opmaak van de R3-laag. Bron: BASE + MOBILE uit `gen3/kit.py`
   (bijlage bij plan 124), vertaald volgens P1–P4:
   - Klassen zijn die van kit.py. Geen klasse staat ook in een `oud:`-blok van studio.css
     (test_r3_css); botsende oude klassen heten daar `<naam>-oud` (bijlage botsingen.txt).
   - De globale elementregels van kit (`*`, `a`, `button`, `p`, koppen) staan onder `.r3`; die klasse
     draagt de schil (stap 6) en de wortel van een omgezet sjabloon. Oude pagina-inhoud valt er niet
     onder. Kits `.app` (de schilhouder) heet hier `.r3-schil`; `.app.m` (telefoonbord) vervalt.
   - Kleuren alleen via tokens.css (P2). Wit op accent wordt de AA-variant (`--accent-knop`,
     `--op-accent`). Elke kit-rgba() is een token (`--scrim`, `--schaduw-*`, `--live-*`).
   - Eén breekpunt 760px (kit) plus één tussenregel onder 1100px (P3). Onder 760px elk tikdoel 44px.
   - Geen style= en geen script als voorwaarde (P4): segmenten en keuzes werken ook als link of als
     echte <input> (`.kz`, stap 4), vensters zijn <dialog>, het filterpaneel een <details>.
   Wordt in E1 één met studio.css. Laadt na tokens.css en studio.css. */
