Roadmap 72, lane 72-materials: LK1 and LK4, one commit each.

LK1: texture map slots

• Inspector > Material > Maps: normal, roughness, metalness, emission, AO, plus tiling, offset and rotation per material and normal and AO strength.
• "Load a set of maps..." sorts files into slots by name (wood_normal.png). setObjectsMapSet is the seam a generated set (PBRnxt, roadmap 58) fills; PBRnxt itself is not in core yet.
• Replicated, one undo step, saved in GLB, scene and presets. Agent materialParams accept the slots.

LK4: look animation in GLB

• KHR_animation_pointer for material and light channels, KHR_node_visibility for visibility, and a new Field of view channel. Camera markers export as glTF cameras.
• The Quest / web preset leaves look animation out and says so in a toast.
• Fix: exporting several objects lost all authored movement, because GLTFExporter wants animations per root.

Proof

• e2e, local slot: material-map-slots 86 checks (two peers, phone 390x896 and 770x850), look-animation-export 69 checks. Neighbours green: animation-bake, animation-look-channels, material-presets, material-types, uv-texture-params, texture-leak, uv-materials, save-as-formats.
• Khronos glTF validator on the exported file: 0 errors, 0 warnings, 10 infos (it does not validate KHR_node_visibility and only partly supports pointers).
• svelte-check 279/39 = baseline; npm run build passes on the final code.
• vitest 3570 of 3570 on two final runs. An earlier run on the same code had 1 failure, and I did not capture which test; it did not come back.

Known red and limits

• material-sharing is red on v1.53.1 too (7.1 and 7.2, late joiner). The lane's last rerun stopped earlier in the same section, at a 90 s boot timeout for the third page, so section 7 has no clean lane result.
• Removing a KTX2 map cannot be undone (no drawable image to restore).
• After a reload, a saved preset cannot name maps it has no URL for.
• Look animation does not read back into the app on re-import (GLTFLoader ignores pointers).
• curveCore is not in v1.53.1, so sampling uses evaluateClip; the pure half can take other samples later.
• The battery time for material-map-slots (640 s) is an estimate from a loaded run; look-animation-export (208 s) is measured.
• Not run on real devices or in VR; owner device rows are in the lane STATUS.
