fix: restore full-guide font scale

The build output went to /dev/null and only the exit code was checked,
which `astro build` returns as 0 even when vite cannot resolve an asset.
Run by hand -- the gate is not in the loop then -- this script would have
force-pushed that build over the live site.

-  database** (`phases`, `handsOnPrompts`, `modelGuide`, `skillSources`,
-  `skillInstallPrompts`, each keyed `{en, pt}`) plus ~12 small `render*`
-  functions that swap `innerHTML` on tab clicks. ~50 `en:` keys. The content
-  should become data; only the tab behaviour is interactive.
-- **`responsive.css`** — a 30 KB append-only layer of overrides bolted on top of
-  `styles.css`. Expect large parts to be dead once layout moves into components.
-  Do not port it verbatim.
-- **`skills-review/catalog.js`** — the real data model of the review desk: one
-  entry per submitted skill with `id`, `author`, `title`, `status`, `focus`,
-  `wins[]`, `improve[]`, `extras`, `improved` (full markdown). 24 entries across
-  `catalog.js` + `submitted-catalog.js`. This is already a content collection in
-  all but name.
-- **`skills-review/files.js` / `submitted-files.js`** — generated file
-  manifests.
-- **`vote.js`** — the vote widget island; talks to `vote-service/`.

+# Assertion removal ledger
+
+`scripts/verify.mjs` may only lose an assertion by adding an entry here. The
+gate counts the `## ` headings in this file and allows exactly that many
+removals below the recorded floor — so a reduction is impossible without a
+written reason landing in the same commit, as a visible diff.
+
+Adding an entry is not a formality. An assertion pins a real contract; removing
+one means that contract is now unverified. Say where it moved, or say plainly
+that nothing checks it any more.
+
+## vote-service one-vote-per-IP contract
+
+**Removed:** 2026-09-06, when `vote-service/` was taken out of this repository.
+
+**What it asserted:** that `vote-service/main.go` contained both
+`X-Forwarded-For` and `one active vote per skill` — the review desk's only
+anti-abuse control, one vote per visitor enforced server-side by source IP.
+
+**Why it went:** there is no file left to read. The check was a substring match
+against source that now lives elsewhere.
+
+**Where it must be re-asserted:** in whichever repository holds the service. The
+deployed service still enforces the contract; nothing in this repository proves
+it. If `vote-service/` ever comes back here, restore the assertion and delete
+this entry.
