Three root causes identified via PageSpeed layout shift culprits: 1. Grid mismatch (CLS 0.495): Critical CSS used `2fr 1fr` but Tailwind compiles to `repeat(3, minmax(0, 1fr))` with `grid-column: span 2`. Updated critical CSS to match Tailwind's exact output. 2. Font swap FOUT (CLS 0.074): @font-face declarations were only in the deferred stylesheet. Moved to critical CSS with font-display:optional and added <link rel="preload"> for weights 400/600/700. Changed all font-display from swap to optional in tailwind.css source. 3. Avatar resize: HTML width/height was 96x96 but CSS sets sm:w-32/h-32 (128px) on desktop. Updated attributes to 128x128.
