v1.3.0 — paste-everywhere & deep upgrades across 12 tools

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

✨ Suite-wide

• Paste anywhere — Ctrl/Cmd+V a screenshot or copied file into any tool; it lands in the drop zone. Snip → paste → done.

🔧 Per-tool upgrades

• Photo Privacy Kit — SHA-256 fingerprints of original vs. cleaned files: cryptographic proof of "same picture, minus the metadata" (gate verifies pixel-identical output)
• Image Shrinker — AVIF output (smallest), batch zip, per-file progress that survives unreadable images
• Scan & Screenshot Cleaner — auto-levels (black/white point stretch) + threshold (photocopy look) + crisper 300 DPI PDF text
• Local E-Sign Pad — optional date stamp under the signature (decoded and asserted by the E2E gate)
• PDF Pages — extract selected pages to a new PDF + insert blank page sized to its neighbor
• Receipt OCR → CSV — per-row expense categories + currency in the CSV (v2 header)
• QR Studio — Wi-Fi / URL / email / phone / vCard presets with spec-correct escaping (;, ,, :, \ — round-tripped through the decoder in CI) + selectable error-correction level
• Audio Trimmer — peak normalize to −0.1 dB before WAV/MP3 export
• Text Diff — similarity % + swap button
• Text Stats — live sentence-rhythm histogram with average words/sentence
• Batch Rename — prefix, suffix, and sequence start number
• Invoice Generator — line-items table no longer overflows narrow phones
