The website adapts its materials to monochrome silver, removes branded textures and adds animated contour lines, reveal/dissolve shaders and light effects. The car is an illustrative concept, not a customer project.

The LED Comfort logo, original fonts, project thumbnails and video assets were supplied in ledcomf-fed3d.zip. The original logo image and its red color are preserved.

The updated interface uses **Unbounded** and **Onest**, self-hosted as Cyrillic and Latin variable WOFF2 files. Both are licensed under the SIL Open Font License 1.1. License copies are in `public/fonts/Unbounded-OFL.txt` and `public/fonts/Onest-OFL.txt`.

The service and advantage diagrams are authored SVG geometry. The contact map uses Leaflet 1.9.4 (BSD-2-Clause; public/licenses/Leaflet-LICENSE.txt) with OpenStreetMap tiles and visible OpenStreetMap attribution. Tile colors are converted to dark grayscale; the red marker is authored SVG tied to geographic coordinates. Route links still open Yandex Maps.

The six video covers in `public/covers/project-01.jpg` through `project-06.jpg` are generated editorial adaptations of the original video thumbnails using the built-in image_gen tool. They use the cars in the source thumbnails as references, with stylized studio lighting and backgrounds. They are cover artwork, not unaltered photographs of completed work. Original video links are retained. The prompt set is stored in `review/covers-prompts.md`.

For faster loading, unused texture coordinates and tangents were removed from the untextured GLB. Positions, normals, indices, materials and scene transforms are retained without loss.
