v1.2.0 — PDF Pages, Text Diff, Text Stats; crop fix; i18n

Live: https://navigatorslab.com/tools/ · Free & open source (MIT) — no accounts, no uploads, nothing retained.

🐛 Fixed (user-reported)

• ✂️ Crop dragging in Scan Cleaner — the preview canvas rendered at full size inside a scroll box and touch drags were hijacked by the browser, so crops silently failed. The image now scales to fit your screen, drags map correctly at any zoom, and touch/pen gestures work. Locked in with a dedicated E2E regression check — verified on production.

✨ Three new tools (12 → 15)

📑 PDF Pages

Reorder, rotate, delete, extract & merge PDF pages — live thumbnails (pdf.js), drag to reorder, rebuild any subset with pdf-lib. E2E-verified: delete one page → rebuilt PDF has exactly the rest.

🔬 Text Diff

Compare two texts with word-level highlights inside changed lines (unit-tested LCS engine), whitespace/case options, unified-diff export. Contracts and drafts never leave the tab.

📊 Text Stats

Live word/character/sentence counts, reading & speaking time, Flesch reading-ease with grade level, and keyword density (Unicode-aware, unit-tested engine).
