User-visible fix

• CSV Cleaner Pro, JSON Studio, and Text Batch Studio input/output textareas now use 16px (text-base) on mobile, retaining 14px at sm and wider, preventing unwanted Safari zoom on focused textareas.

CI reliability fix

• Diagnosed former Lighthouse job stuck building 8,000+ pages after main build; previously attempted .next artifact transfer was also extremely large and its original upload silently omitted the hidden .next directory.
• Consolidated build and Lighthouse into the same runner/job, eliminating the redundant build, artifact upload and download. Set job timeout to 25 minutes to include both checks. Lighthouse assertions retain previous non-blocking behavior; start-server is required.

Verification

• Earlier run 41633441550: typecheck, i18n, SEO, unit tests, normal production build passed, separate Lighthouse build hung.
• New consolidated workflow run 41637032227 is in progress. Do not merge until its results are checked. Not deployed.
