Visual Identity Pass:
- Smooth phase transition overlay with staggered fade-in animation and particle burst
- Building purchase confetti at x10 milestones (gold + green particles)
- Animated resource counters (pulse on gain, shake on loss) - already existed, verified working
Ending Cinematic Enhancement:
- Beacon ending: fade-to-black transition, staggered text reveal, golden light rays,
continuous floating particles, expanded stat summary, 'Play Again' button
- Drift ending: glitch animation on title, fade-in overlay, stat summary with
buildings/projects/clicks/time/phase, dramatic line-by-line log reveal
Accessibility (#57):
- Sound mute toggle button (M key) with localStorage persistence
- High contrast mode toggle (C key) with CSS variable overrides
- Both toggles in fixed bottom-left toolbar with aria-labels
- Keyboard shortcuts M and C added, help overlay updated
- Drift ending button changed to 'Play AGAIN' with proper aria-label
Replace native browser title= tooltips with styled custom tooltips
that match the game's dark theme. Tooltips appear instantly on hover
with building/project name and educational content.
- Add CSS for #custom-tooltip with dark theme styling
- Add tooltip div to HTML body
- Add event delegation in main.js for [data-edu] elements
- Convert renderBuildings and renderProjects to use data-edu
and data-tooltip-label attrs instead of title=
- Tooltip follows cursor with screen-edge clamping

Auto-save game state when the browser tab is hidden (visibilitychange)
or closed/navigated away (beforeunload). Prevents data loss on mobile
where tab switching can kill the page without a save interval firing.

- Stores completion in localStorage — only shows once for new players
- Matches existing visual style (dark theme, accent colors, monospace)
- Start Playing button on final screen with shortcut hint (? overlay)
