+### Social cards
+
+`pnpm build` starts with `pnpm og` (`web/scripts/og/build-og.mjs`), which renders one
+1200x630 PNG per mint and federation into `web/public/og/` from the same API data the
+pages use — satori lays the card out and turns the text into glyph paths (the six
+static TTFs under `web/scripts/og/fonts/` are the same faces the site uses),
+`@resvg/resvg-js` rasterises it. No browser involved; a full run of ~70 cards takes a
+few seconds, and a rerun with unchanged data renders nothing: each card's inputs are
+hashed into its filename (`mint.example.com.a1b2c3d4e5.png`) and
+`web/src/generated/og-manifest.json` records what is already on disk. The hashed name
+is also the cache-busting story — link-preview scrapers cache an `og:image` by URL, so
+a mint whose rating moved or that went offline gets a new URL on the next scheduled
+rebuild, while the stable-named `default.png` (brand plus network stats, used by every
+non-mint page) is served with a one-hour cache instead (see the nginx block below).
+
+The images are one English render shared by every locale; titles, descriptions and alt
+text translate per page. Relative times stay out of the PNGs on purpose — a "3d ago"
+would go stale inside a static file — so the cards carry absolute month/year stamps,
+and the one exception, the "Offline {n}d" chip, is derived from a day-granular clock so
+it regenerates at most once a day.
+
+`pnpm og:fixtures` renders the six edge cases in `web/scripts/og/fixtures.mjs`
+(30-character name, no icon, zero reviews, offline, melt only, announced-only
+federation) into `web/og-fixtures/` at a pinned timestamp; those snapshots are
+committed, so eyeball them after any template change.
