Classic gradient could be a healthy precomputed oklab or oklch precomputed interpolation

this would make the classic gradient shine / be higher fidelity to the HD gradient. reducing competition between the two and helping rise up even the classic gradient.

The issue names only the classic and HD gradients, not files, tests, or an entry point. Start by locating those two gradient implementations and checking how interpolation is currently performed. Done means the classic gradient uses a healthy precomputed OKLab or OKLCH interpolation and has visibly higher fidelity to the HD gradient.
