/**
 * Palette wrapping: traverse a ramp coordinate through `cycles` half-cycles as `t` rises, folding
 * back at the ends (triangle wave, so any palette stays seam-free). Band density is |∇t| × the
 * cycle count — automatically dense where the field bends/pinches and smooth elsewhere. Identity
 * at cycles = 1. Where the band frequency exceeds what a pixel can resolve, fade to the palette
 * mid instead of shimmering (the quilezCheckerFilter limit idea) — derivatives are legal, `t` is
 * a fn parameter computed in uniform control flow. Fragment-only (fwidth).
