CT volume view (lib/ctvolume.js, lib/ctsource.js): a cube of the raw X-ray scan around a picked papyrus point (256 voxels, 128 on phones) as a Data3DTexture, raymarched MIP clipped to an oriented slab that starts square to the surface; own canvas beside the scroll, render on demand; panel group (Pick a point, Show volume) and floating panel with slab, tilt, window/level, size and detail controls; Settings, unrollView.ct.volume API and actions, ?ctvol URLs, scanGeom and scanPick hooks in app.js, glossary (MIP, slab, CT volume, raymarching), docs

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

Public API at window.unroll (schema, help, coverage test; ui and bench groups), embed mode with postMessage bridge and oEmbed, version 0.9.4 in About and API, ink_9um (9 µm) label and credit, Ink Bench hardening from the audit, hashchange without reload, capped test hooks
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
