+Output lands in `api/dist/` and `web/dist/`.
+
+### Live lists
+
+The prerendered mint list is a snapshot of what `GET /api/mints` said when the build ran.
+It used to stay that until the next build, which is why there was a nightly timer: a mint
+indexed at noon was reviewable at once — the 404 resolver saw to that — and had no card on
+`/mints` until 03:30, beside cards whose ratings and statuses were equally old.
+
+`/mints`, `/fedimints`, `/lnurl-mints` and the home page's three top-six strips now refetch
+that endpoint once, after paint, and rebuild their grids from the answer. One request per
+page, no relays involved: card counts have always come from the API's ingested review
+aggregates, and review *bodies* remain a mint page and `/reviews` concern.
+
+**The prerendered cards stay.** They are the first paint, they are what a crawler indexes,
+and they are the whole page for a reader with no JavaScript — `<noscript>` already unhides
+them, and the search, sort and filter controls act on whatever is in the DOM. Hydration
+only ever replaces them with something newer, and never with nothing:
+
+- a failed fetch does nothing at all, silently — a grid that is correct as of the last
+  build is a far better answer to a flaky network than an error about a list already on
+  screen;
+- an API answering `[]` also does nothing. Serving an empty index is the failure the
+  [build gate](#rebuilds) exists to catch, and a page that rendered it as "no mints" would
+  be that bug wearing a different hat;
+- whatever the reader had already set — a search they typed, a sort they picked, "hide
+  offline" — is re-applied to the new cards, so a refresh landing mid-interaction cannot
+  undo it.
+
+Two pieces make it work. `web/src/lib/mint-cards.ts` is `MintCard.astro`'s browser twin,
+the same relationship `review-cards.ts` has with the reviews panel: identical classes and
+identical `data-*` attributes, because the sort keys, the search fields, the rank chips and
+the shared-element view transitions are all read off the DOM. And `MintListItem` carries
+the facts a chip is drawn from — `nuts`, `capabilities`, and the LNURL withdraw ceiling and
+funding flag. Those replaced an N+1: `/mints` and `/lnurl-mints` each used to fetch
+`GET /api/mints/:host` once per mint at build time to read two booleans off it, which is
+tolerable on a build machine and unthinkable in every visitor's browser.
+
+Strings come from the page's own inlined catalog, so a hydrated Spanish card says "En
+línea", "54 reseñas" and "4,9", and its link is `/es/mint/…`. The one thing hydration
+cannot improve is the home page's sentiment bars: the build gives those six cards real
+rating distributions from a per-mint detail fetch, and the list payload has no
+distribution in it, so a refreshed card falls back to the rating proxy the index pages
+have always used.
+
+ Every page is prerendered once per language, so ~55 mints
 and 9 static routes come out as ~200 pages, each with real titles, meta descriptions,
 OpenGraph and Twitter tags, a social card, a self-referencing canonical, a full hreflang
 set and a JSON-LD graph. `sitemap.xml` lists every indexable one with its `xhtml:link`

 ### Rebuilds
 
-Mint pages are prerendered, so new mints and new review counts appear at the next build.
-A nightly rebuild is enough; the site stays correct in between because the islands
-refresh status and reviews at runtime, and an unbuilt mint still resolves through the
-client-side fallback on the 404 page.
+**Builds happen on deploy. There is no timer.**
+
+```bash
+sudo systemctl start cashumints-web        # build, then publish
+```
+
+There used to be a `cashumints-web.timer` firing at 03:30 nightly, and it was load-bearing:
+the mint list was a snapshot of whatever the API held when `astro build` ran, so a
+rebuild was the only way a new mint, a new review count or a changed status ever reached
+`/mints`. The list hydrates now — one `GET /api/mints` after paint, see
+[Live lists](#live-lists) — so all three reach the page within a second of load, in every
+language, and rebuilding 2,000 pages overnight to refresh numbers that refresh themselves
+is twenty minutes of CPU for nothing.
+
+What a build still produces, and therefore what a deploy is still for:
+
+| Still built | Still stale between deploys |
+| --- | --- |
+| The prerendered HTML a crawler reads | The `ItemList` JSON-LD on the index pages |
+| A social card per mint | The card for a mint indexed since the deploy |
+| `sitemap.xml` and the hreflang set | A `/mint/{host}` page for a mint indexed since the deploy |
+
+That last row is the one to know about. A mint indexed today has no prerendered page of
+its own until the next deploy: `/mint/newhost` returns **404**, and the 404 page's
+resolver looks the address up against the live API and renders it — readable, reviewable,
+linkable, with a `noindex` on it until the deploy gives it a real page. That was already
+true between nightly builds; dropping the timer only lengthens the window.
+
+Deploy when you ship code, or when enough new mints have accumulated that their pages are
+worth prerendering. Nothing breaks if you do not.
 
 Publishing is a separate step from building, and the separation is the point: the copy
 the site server reads is only touched once a build has succeeded, so a failed build
