Reimplements Tangled PR #5 (tomaslatal.cz) on current main — a straight rebase was impossible (the tree diverged heavily since Sep 19: es/pt/barcelona, the config refactor, verifiers). Promotes .cz from a coming-soon placeholder to a full build scope. - scopes.ts: cz scope, EN/CS, grey/cobalt flag lockup (white->grey + cobalt blue; UI leads grey, distinct from .pl grey/red and .no red/cobalt), manager @tomaslatal.cz, six cities, social @atproto.cz. - i18n: the NATIVE Czech (cs) UI catalogue from the PR author (a Czech speaker) — ships reviewed, unlike the machine-authored packs. cz uiByScope (en+cs), REGION/IN_COUNTRY/ENDONYM/OG_LOCALE, community-size Czech strings. - communities.ts national entry; deploy.yml builds + publishes cz; removed cz from the coming-soon network strip + the prospective brand lists; brand assets regenerated (grey/cobalt). DNS note: atproto.cz still points at Cloudflare, not Codeberg Pages, so the built site will serve only once its A/AAAA are repointed (same as Barcelona).
