Address review-panel blockers (a11y, contrast…

Details

Round 1 of the 5-reviewer panel surfaced concrete blockers; this resolves all:
- mobile hero now leads with the headline/lede; portrait drops below it
- stronger hero scrim + a translucent marquee band keep text/affiliations
  legible over weather in every season and theme
- primary CTA + ::selection use a deeper accent (AA: white on #b23c0c ~5.9:1);
  light-theme accent darkened to #b23c0c so inline accent text clears 4.5:1
- publication parser: recognise mixed-caps venues (NeurIPS/arXiv) for badges,
  and render first-author entries that omit the name string (no junk venue)
- stats never render 0: seed real counts; DB refresh only overrides when >0
- command-palette input is a valid ARIA combobox (role + aria-expanded)
- lead with the interactive explainer; demote stats below projects
