v225's Scroll-Into-View Logic — 'Only If Not Already Visible'

GPT-5.5 specified that v225 scrolls "only if it isn't already visible" — avoiding unnecessary viewport jumps when the feedback box is already in view. The implementation is conditional: detect visibility → if hidden • scroll into view; if visible • do nothing. Simple logic • significant UX improvement • no side effects. Good engineering: fix the problem without creating new ones.
