TPP: shrink the scaling-laws widget to fit a laptop…

Details

Scrolled so the section title sits under the fixed nav, the intro + card
ran ~250px past a 14" MacBook fold (~300px at "Larger Text" scaling). Now
the title and the whole widget fit together at default 14", and the card
alone fits every screen from a short 13" to a 27" monitor.
Card 856 -> 611px (coverage phase); title-anchored overflow 250 -> ~11px.
- Stage: fixed aspect-ratio 16/8 (~509px) -> height clamp(272px, 37vh,
  350px), so the plot tracks the viewport (274px on a short 13", 315px on
  a 14", capped 350px) while staying full-width and legible.
- Compact section intro: one-line title (clamp max 3rem -> 2rem), a
  smaller 3-line lede (1.08 -> 0.92rem, trimmed copy, kept the
  published-runs link), tighter head gap, and reduced outer padding.
- Trimmed the caption reserve (6.4 -> 3.9em) and every chip / controls /
  window / legend row margin.
Verified headless across 13"/14"/16"/27" and phases 0-4, light, mobile:
plot, axes, coverage brush, HUD, caption, legend stay legible. No
functional change -- 16/16 core tests, tsc clean, controls animate,
persistence intact, zero page errors.
