ONE file, TWO surfaces. `editorial_board.py::_socialize_client` splices it into the board's page logic between the socialize-client marker comments (the block is rebuilt from this file on every run, so editing here is what ships); the event pages carry the same text as their whole `logic`, written by build_event_pages.py. The mode is chosen at runtime, not build time: - BOARD : one target per card, `.nvb-card[data-ref]`. - PAGE : the event's own page, keyed by `data.uid` (`@`), control placed in the action row next to the CTA buttons. THE RULE THIS IS BUILT AROUND — socialize is the SOCIAL layer, not an event directory: 1. It must NEVER expose a list of events. The feed is scraped from third parties; publishing it back through this API would hand out the whole harvested set and advertise that we hold it. So this client does NOT call /api/v1/events, does not page it, does not index it, and does not match rows against a socialize list. (The API closed that endpoint to anonymous callers in 0.4.0 — 401 — and this client never asked for it anyway.) 2. When socialize is asked about an event it answers with the SOCIAL FACTS ONLY — how many people are interested, whether the viewer is one of them — keyed by an identifier we already hold. No title, date, venue, price, source or provenance comes back, so nothing on the page, in a response or in a log discloses that we know about that event, or how. 3. THE KEY IS OPAQUE. We address an event by `ref`, a hash of its source id and date (szRef, below) — never the uid itself. The uid is the source's own identifier (an Eventbrite ticket number, say); the ref travels to socialize in request paths and sits in our served HTML, so sending it raw would disclose where we scraped the event and let anyone holding it look the source up. HOW THE SESSION WORKS — this is what makes "I'm going" possible at all. The API accepts its `socialize_session` cookie as well as a Bearer token; the cookie is SameSite=Lax; and socialize.nevente.com shares this site's registrable domain, so a request from this page is SAME-SITE and the cookie is sent (Safari's ITP treats it as first-party for the same reason). That is why every request below sets `credentials:'include'` and why the API's CORS answers with the exact origin plus Allow-Credentials. The magic link lands on the API itself (there is no return URL in the contract), so the flow is: click -> sign in by email -> open the link (the cookie is set there) -> come back. The ref of the interrupted click is remembered as `pending` so it completes by itself on return. Page logic runs as `AsyncFunction('data','api','window')` TWICE — server-side for the render, then in the browser. `api.fetch` is the only fetch in both (SSR binds globalThis.fetch, the browser window.fetch); `window` is an SSR SHIM with only `location`, so `document` and `localStorage` are probed with `typeof`. THE SSR RUN NEVER FETCHES FACTS: they are per-event, so a board of 74 cards would be ~74 requests per phone view (155+ desktop) and would stall the render. The server asks only /info; the browser fills counts in lazily, per target, as it comes near the viewport. The API base can be overridden with `data.board.socializeApi`, and the copy with `data.board.socializeText` — set them on the shared block `blocks/nevente-events`' data, because the board's block fetch assigns `data.board` wholesale. */ const SZ_BASE = String((data.board && data.board.socializeApi) || 'https://socialize.nevente.com').replace(/\/+$/, ''); const SZ_API = SZ_BASE + '/api/v1'; const SZ_SESSION_KEY = 'socialize_session'; // a Bearer token, if one was ever stored const SZ_PENDING_KEY = 'socialize_pending'; // ref waiting for a sign-in to complete the click const SZ_FAV_KEY = 'socialize_has_favs'; // '1'/'0': does this viewer have favorites? asked once const SZ_TIMEOUT_MS = 4000; // SSR must not hang the render on a slow API const SZ_IS_DOM = (typeof document !== 'undefined'); /* Copy, overridable from the block data so wording changes need no code change — the board has `board.labels`, but an event page has no board at all. */ const SZ_TXT = Object.assign({ going: 'Do të vij', goingOn: 'Po vij', interested: 'të interesuar', interestedOne: 'i interesuar', signTitle: 'Do të shënosh pjesëmarrjen?', signLead: 'Të dërgojmë një link identifikimi.
