showing cursor coords and f₁(x)…f₈(x) values simultaneously
- Up to 8 color-coded functions with inline color pickers and
visibility toggles
- Discontinuity detection for functions like tan(x)
- Adaptive grid labels that rescale with zoom
- Responsive layout: 2/5–3/5 split on desktop, tabbed on mobile

- Rename ColorPage → ColorManipulation (no AppPage wrapper inside)
- Move AppPage + title/description/icon to color/page.tsx, consistent with other tools
- AppPage now accepts icon prop directly; removes internal usePathname lookup and 'use client'
- All tool pages pass tool.summary as description and tool.icon as icon

Add a sixth tool with live SVG preview, customizable foreground/background
colors, error correction level, margin control, and export as PNG (256–2048px)
or SVG. URL params enable shareable state. All processing runs client-side
via the qrcode package.
