Campanie multi-stil — PR1 (T1-T8 + TD1-TD6)

Adauga al 6-lea stil de joc: campanie multi-stil care leaga puzzle-urile
in camere de stiluri diferite (clasic/terminal/arcade/chat/point in rotatie),
conectate prin coridoare cu usa, litera si stele.

Contract de montare (verificat la gate T1):
- gameCampaign: un <iframe srcdoc> per camera; camerele cheama parent.*
  pe un nivel (merge si pe file://); template per stil cu sentinel __CFG__
  injectat prin replace-functie (D1) + json.replace(/</g,'<') (D6)
- roomReady/roomError + timeout 4s -> skip cu 0 stele + cod eroare;
  idx detinut de parinte, accepta nextRoom doar de la contentWindow activ (D5)
- parent.beep in mod campanie (un singur AudioContext, D2)
- resume prin safeStore try/catch (D3) + cheie djb2 peste CFG embedat (D11)

Builder:
- selector de stil per puzzle ("Auto (stil)") + optiunea Campanie multi-stil
- normalizePuzzle() la load + import (sursa unica pt forma puzzle, D8)
- blocare export+preview la 0 puzzle-uri; persist() guarded (D12)
- letter normalizat [A-Za-z0-9] + esc la SVG point (D13)

Design (DESIGN.md): tokens --c-*, intro poster, coridor "usa ca erou",
chrome unica sursa de progres, 5 usi CSS/SVG (normal/stuck/crescendo),
mod camera per motor, buget vertical mobil, baseline a11y.

Tooling: tests/smoke.mjs (Playwright, zero-dependente prin npx), TODOS.md,
sectiune ## Testing in CLAUDE.md. Demo-uri regenerate + exemplu-campanie.html.
