- Solver: cubejs-backed two-phase solver, lazy-loaded chunk so the ~80 KB table-init cost stays out of the main bundle. New cube-to-facelets converter (3D model -> 54-char URFDLB string) verified bit-for-bit against cubejs's own move() output. - Solve button in ControlsPanel with disabled "Solving..." state, wired through the CubeView controller; animates each move sequentially. - Rewrite solved-check to the WCA face-uniformity definition. The old strict "identity quaternion per cubie" check rejected center spins (invisible) and whole-cube rotations, both of which are still solved per WCA / Kociemba. - Vitest specs under tests/ cover cubie-model, move-definitions, move-parser, apply-move (4x turns, inverses, sune order=6, R2 == R R), scrambler, solved-check, algorithm-runner, cube-to-facelets, solver. 39 tests, ~3 s. Adds npm test / npm run test:watch scripts.
