playTime was defined in globals but never incremented and never
included in save/load. Now incremented each tick and persisted
in localStorage via the whitelist and save data.
applyFn was multiplying G.codeBoost by 0.7 on every updateRates() call
(building purchase, project, click, etc.), permanently degrading it.
After 10 calls the boost was effectively zero.
Fix: apply penalty to G.codeRate (computed per-tick) instead of
G.codeBoost (persistent multiplier). Debuffs must never mutate boost state.
- index.html: role=region on phase-bar, strategy-panel; role=dialog+aria-modal on help overlay, offline popup, drift ending; aria-label on help button, close button, continue button, start over button; aria-live on progress label
- render.js: aria-label on alignment event buttons; fix exportSave() URL revoke race with setTimeout delay
- engine.js: aria-label+aria-pressed on buy amount buttons; role=button+tabindex+aria-expanded+aria-controls on completed projects header
- Building rate display now shows actual boosted rates (after multipliers)
instead of raw base rates, so players see their real production
- WRITE CODE button area now displays current click power dynamically
(updates each render tick as boosts change)
- Click power also reflected in button aria-label for accessibility
