Build a "Hold-to-Confirm Button" React component.

CONCEPT: A 'Delete project' button that replaces a confirmation modal: the user holds it, a fill grows across it, and only a full hold completes the action.

LAYOUT & CONTENT:
- Cream button, 1px charcoal border, label 'Hold to delete' with a trash-like icon; a terracotta fill layer behind the label, scaleX 0 initially.
- After completion the label changes to 'Deleted' with a check and the button locks for 2s, then resets.

INTERACTIONS & MOTION:
- On pointerdown animate fill scaleX to 1 over 1.2s linear; on pointerup/leave before completion animate back to 0 with spring stiffness 300 damping 30.
- During the hold, the button shakes subtly (x ±1px) in the final 300ms.
- Keyboard: holding Space or Enter behaves the same; aria-live announces completion.

DESIGN SYSTEM (non-negotiable):
- Palette: paper background #FAF9F6, deep charcoal #121212 for text and 1px borders, ONE warm accent: cobalt #1D4ED8 or terracotta #D9534F. Secondary surface #F2EFE8.
- Typography: Swiss / editorial. A tight grotesk for UI (Instrument Sans, Inter Tight or similar) with negative tracking on display sizes; an italic serif (Instrument Serif) used sparingly for one emphasized word.
- NO dark-mode neon, NO glow, NO glassmorphism, NO backdrop blur, NO purple-to-blue gradients, NO emoji icons. Solid fills, hairline rules, honest shadows (hard offset or none).
- Motion: Framer Motion with spring physics (type: "spring", stiffness 300-500, damping 20-35). Animate transform and opacity only. Respect prefers-reduced-motion via useReducedMotion().
- Icons: lucide-react, 1.5px stroke.
- Accessibility: real <button>/<a>/<label> elements, visible focus ring (2px cobalt, 3px offset), keyboard operable, aria attributes where state changes.

OUTPUT: one self-contained React component file (Tailwind CSS v4 utility classes, framer-motion, lucide-react), no external images, default export, ready to paste into a Next.js App Router page with "use client".
