Dental Clinic Tactile Action Buttons

Build a "Dental Clinic Tactile Action Buttons" React component.

CONCEPT: Primary and secondary actions for "Smile Lab" that feel like physical keys.

LAYOUT & CONTENT:
- Primary: 'Book a visit', fill #1D4ED8, 1.5px charcoal border, hard shadow 4px 4px 0 #121212.
- Secondary: 48px square cream icon button with a lucide 'Sun' icon.

INTERACTIONS & MOTION:
- Primary whileTap: translate 4px,4px and shadow to 0 (spring stiffness 600 damping 20).
- Secondary: on click the icon rotates +360° with spring and the button squashes (scaleY 0.9).

DESIGN SYSTEM (non-negotiable):
- Palette: paper background #FAF9F6, deep charcoal #121212 for text and 1px borders, ONE human 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".
