Retune the GPU clear colour on both render paths (Metal on iOS, GL on desktop) from the old dark navy (0.05,0.06,0.10) to a candy-lavender tone sampled from the regenerated background's mid-gradient. The dark navy was the one off-palette constant left after P12.1/P12.2; the background art covers the full drawable in steady state, so it only ever surfaced as a pre-load flash / potential dark seam. A single shared CLEAR_R/G/B keeps the two paths from diverging. Refresh the stale full-board goldens (p4_board, p9_polish), which still showed the pre-P12.2 dark HUD, to the current cohesive candy palette.
