What

Adds pnpm size: runs the production build, then scripts/check-bundle.mjs measures every JS/CSS file in dist/client/assets (gzip level 9 and brotli), groups by chunk name without the content hash, and compares with the committed size-budget.json.

• Budget = size on the base branch + 5% margin, for total JS, total CSS and every chunk of 4 kB gzip or more. Chunks without their own budget fail above 8 kB, so a new large chunk is caught.
• Prints a table (current, budget, difference) and writes dist/size-report.json for CI to upload later.
• pnpm size:update rebuilds and rewrites the budget when growth is intended.
• No application code changed. ESLint gets Node globals for scripts/*.mjs.

Verification

• pnpm size on the base branch: exit 0 (total JS 415.3 kB gzip vs budget 436.1 kB).
• With import * as ts from 'typescript' added to app/router.tsx (reverted afterwards): exit 1.

TOTAL js   gzip   1357.6 kB   436.1 kB   +921.5 kB   OVER
hydrate.js gzip    981.1 kB    40.9 kB   +940.2 kB   OVER
Bundle budget exceeded in 4 measurement(s).

• typecheck, lint (0 errors), format:check, check:manifest: exit 0.
• test:coverage: 4 failures in ProductDetails.test.tsx (localStorage.clear undefined) also fail on the unmodified base branch when run on Node 26 locally; the repo pins Node 22 in CI.

Confidence Score: 5/5

The PR appears safe to merge; no actionable issues remain.

Summary

Adds pnpm size to build the theme and check compressed JS and CSS sizes against committed limits.

• Bundle checks compare each build with saved size limits.

@greptileai please review this pull request.

[salahmyn]

This branch conflicts with the base branch feature/quality-gates-twig-parity-audit, which has moved (CI, knip, F4 and F7 are merged), so CI and the review have not run on it. Please rebase on the base branch, resolve the conflicts (likely package.json and pnpm-lock.yaml), run build, typecheck, lint, format:check, test:coverage, check:manifest and knip, push, and wait for the Greptile review and the Quality gates check to pass.
