The designer's archive for the LED strips, kept unchanged under source/: Issue-662-LED-light-spec-2026-10-01.zip attached to #662 (comment) (archive SHA-256 of every member in source/MANIFEST-SHA256.txt; all six checksums verified when the files were copied). The Figma section is Led Light, 626:34 with the frames Led On (626:35) and Led Off (626:53).

The contract is the ТЗ in the body of #780, not the archived source/TZ-issue-662-LED-strips.md. Where they differ the issue wins — notably the 30 cm default radius (#784), the white core under Glow, editing in the Devices editor and the product's state-invariant thickness 0.12 D instead of the mockup's pixel sizes and blur. These files are documentation only; nothing here reaches the runtime bundle.
