Type and spacing scale (CSS variables) for every panel and button: 14 px floor and normal tracking on phones, 1.5 body line height, balanced button padding and icon gap, safe-area insets, phone landscape layout, layer labels that wrap cleanly, panel kept clear of the header and credit
Overlay textures upload through a per-frame queue (about 6 ms per frame, initTexture) instead of all at once, removing the 14.6 s main-thread freeze; import map versions for tear.js, damage.js and lib/*.js; scan shown as 9.4 µm with 9.362 µm voxels in the details; glossary links every occurrence; mobile panel clears the bottom bar
Control panel redesign (ui.js, ui.css): grouped Layers, Ink Bench, View, Destroy and Scrolls with icon and text labels, 44 px targets, pressed states, shortcut tooltips, focus rings, docked mobile panel; Settings (quality, reduced motion, speed, glow, background, HUD, labels, sensitivity, units, Ink Bench button) saved in localStorage and settable by URL; agent API unrollView.actions/settings/state/glossary (docs/AGENT_API_UI.md); plain language glossary.json under About with linked terms; faster intro (motion within one frame, ease-out, about 2.5 s, skip with Enter or button, follows speed) with shaders compiled behind the loader; CPU pick fallback for Destroy on GPUs without float targets; readout panel, fixed Roll up width, header clear of the panel
