Sidebar expanded width 140px -> 200px and collapsed 60px -> 64px to
match mockup proportions. Hero banner now uses a fixed shorter height
with object-fit cover, a bottom mask fade, and a radial vignette so
its edges blend into the page background instead of sitting in a
bordered box. KPI cards are now semi-transparent so the hero image
bleeds through behind them.
