dejank

Detect and diagnose visual jank in React UIs. Covers two modes -- static analysis of code patterns that cause flicker, layout shift, and flash of intermediate state (for pre-merge review or preventive sweeps), and runtime investigation of specific visual symptoms (flicker, blink, jump, stutter, remount churn, scroll reset, post-paint correction). Use when the user mentions jank, something feeling off, flashing, blinking, layout shifting, full repaints, or wants a render stability audit.
