🌈 Method A — swap ONLY the sparkles, character untouched

VERIFIED: the turtle is byte-for-byte identical to your art — 0 changed pixels outside the 3 sparkle spots. Your character was NOT redrawn.

BEFORE

AFTER — 4-point sparkles puffed

Decide: the design still has a couple of 5-point stars left sharp (per scope). They're now a bit inconsistent with the puffed sparkles + a mild thin-ink risk. Want those puffed too (one flag) for a uniform look, or leave them?
