Sonnet Integration Draft v1 — 2026-03-26
What's new vs base architecture (site/index.html):
CANVAS:
- Multi-color star field: cool white, warm white, pale blue, pale gold, faint red
- 4 size classes: pinpoint, small, medium, bright (per aesthetic brief distribution)
- 3 depth layers for parallax (far/mid/near) moving at different scroll speeds
- 2-3 nebula washes: very faint radial gradients in blue-magenta and teal
- Twinkle speed varies by size: bright=slow, pinpoint=fast, some steady
- Canvas draws nebula layer beneath stars
SCROLL MECHANICS:
- Parallax: star zone transforms on scroll, depth layers shift at 0.1/0.3/0.5x
- Descent uses JS-driven smooth scroll with easing, not native scroll-behavior
- Mode switch: body overflow toggled properly, scroll position managed
- Return-to-stars: scrolls up with easing, then locks overflow
CONSTELLATION LINES:
- Subtle opacity pulse animation via CSS (not JS - saves canvas cycles)
- Pulse timing staggered per line
KEYBOARD NAV:
- Brief directional indicator shows which direction you're navigating
- Focus ring is the amber glow (no additional outline)
- Smooth visual transition between stars
ACCESSIBILITY:
- prefers-reduced-motion: disables twinkle, parallax, pulse animations
- aria-live region announces current star name on navigate
- Focus trap in lightbox properly cycles between Enter button and overlay
- role="navigation" on star zone, role="region" on content zone
- Skip-to-content pattern: first Tab from star zone focuses back-btn
MOBILE:
- Touch: tap star to select, tap-and-hold shows label (via CSS :active)
- Star dots enlarged to 12px on mobile for touch targets
- Billboard nav gets larger touch targets on mobile
- Canvas reduces star count on mobile for performance
- Nebula washes simplified on mobile (1 instead of 3)
SKYLINE:
- Varied billboard colors: some amber, some teal, one green
- Faint ambient glow between buildings (canvas or CSS)
- Buildings get teal edge-light on one side
- Bioluminescent accents on some building surfaces
PERFORMANCE:
- Canvas uses a single offscreen buffer for nebula (drawn once, not per frame)
- Star draw loop uses pre-computed color strings
- Parallax uses transform (GPU composited) not top/margin
- resize debounced to 150ms
