Przewidywany koszt to ok. 0,25–0,40 USD za run.\n- `cron/scrape.ts` czyta wynik ostatniego udanego runu, także uruchomionego ręcznie w konsoli Apify.\n- Z wyników odpada wszystko dalej niż 80 km od Zamościa, a także wycieczki, pielgrzymki i wydarzenia online.\n- Zdjęcia z FB nie są zapisywane, bo ich linki szybko wygasają.\n- Wydarzenia z FB mają najniższy priorytet, więc scalają się z tymi samymi wydarzeniami z innych źródeł.\n\n👉 Add APIFY_TOKEN here: https://www.val.town/x/dominik1/co-w-zamosciu/environment-variables?key=APIFY_TOKEN\n- Tytuły filmów z repertuarów pisanych wersalikami dostają poprawną wielkość liter od AI (z cache).\n- Nie da się pobierać automatycznie: Arabeska (ogłasza tylko na Facebooku i Instagramie). Takie wydarzenia dodajesz przyciskiem ＋.\n- To samo wydarzenie z kilku stron jest scalane w jedno. Decyduje ten sam dzień, zgodna godzina i podobny tytuł.\n- Wydarzenia, których reguły nie przypisały do kategorii, klasyfikuje AI (`std/openai`, gpt-5.4-nano). Wystarcza darmowy limit Val Town.\n- **`cron/digest.ts`** codziennie o 8:00 wysyła push na telefony (Twoje „Idę” są na początku) i mail do właściciela. W piątek dochodzi zapowiedź weekendu i ostrzeżenia o źródłach, które przestały działać.\n- **Dodawanie ręczne** (przycisk ＋, wymaga PIN-u): wklej tekst z plakatu, posta z FB albo link, a AI wypełni formularz.\n- Stan źródeł: `/api/status`.\n\n## Zmienne środowiskowe\n\n- `ADD_PIN`: PIN do dodawania i ukrywania wydarzeń.\n- `VAPID_PUBLIC_KEY`, `VAPID_PRIVATE_KEY`: klucze Web Push.

Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
