+//   e.g. node scripts/release/rehome-open-prs.mjs 3.8.49 3.8.50
+//
+// WHY THIS EXISTS AS A SCRIPT AND NOT A `gh pr edit` LOOP IN THE SKILL:
+//
+//   1. `gh pr edit --base` FAILS SILENTLY (v3.8.42 lesson). It exits 0 while
+//      leaving the base untouched — so every edit MUST be read back with
+//      `gh pr view --json baseRefName`. A hand-run loop skips that under
+//      fatigue; this does not.
+//   2. Volume. At the v3.8.49 freeze there were 148 open PRs on the release
+//      branch — ~450 API calls between edit, verify and comment. That is not a
+//      thing a human does reliably at 2am mid-release.
+//   3. `gh pr list` defaults to **30 results**. A loop written without
+//      `--limit` silently re-homes the first 30 and reports success.
+//
+// Idempotent: a PR already based on release/v<next> is skipped, so a resumed
+// release re-runs this safely.
+//
+// NOT covered here (by design): PRs opened AFTER this runs. Those are handled
+// by flipping the repo's default_branch to release/v<next> at 0a.0b — see the
+// skill. Contributors open PRs against the default branch; if that still points
+// at `main`, they never target a release branch at all.

+// #6815 — Provider Quota page horizontal density.
+//
+// #6815 changed QuotaCardGrid.tsx's per-group card grid from a
+// single-column-only layout (`flex flex-col`) to one that packs multiple
+// QuotaCards side by side on wide screens, instead of stacking every card
+// vertically no matter how much horizontal space is available.
+//
+// That guarantee was only ever asserted *incidentally*, by two other guards
+// that pinned the literal Tailwind token the #6815 implementation happened
+// to use at the time (`sm:grid-cols-2` in
+// tests/unit/quota-card-grid-mobile-7072.test.ts and
+// tests/unit/quota-card-grid-horizontal-layout.test.ts). When PR #7027
+// migrated the component from a fixed breakpoint ladder
+// (`grid-cols-1 sm:grid-cols-2 md:grid-cols-3 xl:grid-cols-4`) to a
+// container-driven auto-fit template
+// (`grid-cols-[repeat(auto-fit,minmax(min(100%,280px),1fr))]`), that literal
+// token disappeared from the source and both guards were edited to stop
+// asserting it — silently deleting the only coverage #6815 had.
+//
+// This guard re-establishes dedicated coverage for the #6815 density
+// guarantee itself, decoupled from *how* the component achieves it. Instead
+// of matching a specific class-name token, it simulates, from the shipped
+// className(s), how many columns the per-group card grid would actually
+// render at a wide container width — supporting both mechanisms seen in this
+// component's history (a Tailwind breakpoint ladder, and a CSS auto-fit
+// `minmax()` template) — and asserts that count is >1. Reverting to a single
+// unconditional column (`grid-cols-1` with no responsive/auto-fit variants,
+// or dropping the grid entirely for `flex flex-col`) must fail this guard,
+// regardless of which mechanism produced the regression.
