✨ New tool

🔳 QR Studio (tool 12)

Generate and decode QR codes entirely on-device:

• Generate — text or URLs → auto-sized module grids at 256–1024 px, custom foreground/background colors, optional spec quiet zone, PNG (crisp, nearest-neighbor) and vector SVG export
• Decode — drop any QR image; jsQR reads it on-device with both inversion attempts (dark-on-light and light-on-dark). Wi-Fi passwords, links, and ticket codes never leave the tab.
• Proven in CI — the E2E gate encodes a unique payload, exports the PNG, feeds those exact bytes to the decoder, and asserts a character-for-character match — locally and on production.

🖼️ Social previews

• 13 rendered 1200×630 Open Graph images — one per tool plus a refreshed suite banner — each wired into its page's og:image/twitter:image, so every tool looks right when shared.

⚡ Lighthouse: 98–100 everywhere

All 13 pages audited across performance, accessibility, best-practices, and SEO:

• Performance (was 77–84 on 6 pages) — pdf-lib now lazy-loads only when a tool actually exports, keeping first paint fast
• Accessibility (was 74–93) — accessible names on every select/input, WCAG-passing accent-on-dark text

🔐 Verification gate (now 37 checks + Lighthouse)
