codeweb v0.7.0

Changed (the report finally looks like the product it is)

• A validated color system replaces generated hues. Area colors were hsl(i × 137.5°) —
  unbounded spun hues; the treemap ramped green→red at full saturation (measured deutan
  ΔE 2.2 — invisible to red-green-deficient viewers). Now: a fixed-order 8-slot categorical
  palette validated against the actual dark surface (worst adjacent ΔE 8.4 protan / 19.3
  normal, all ≥3:1; 9th+ areas fold to neutral), a single-hue slate→red lightness ramp for
  duplication density (with an on-canvas legend), reserved status colors for finding
  severity, and the brand lime demoted to what it should be: UI accent (selection, focus),
  never a data series.
• The graph is drawn like a product. Focus + context replaces expand-everything: every
  area starts as a bubble and clicking one expands ITS symbols in place — the all-at-once
  hairball is impossible unless explicitly asked for. Curved weight-scaled edges; node fills
  with darker same-hue rings; halo labels in the real UI font (the canvas font stack fell
  back to a serif before); the tangle color only appears where it means something; search
  reveals a hidden symbol's area instead of saying "no matches"; positions persist across
  expansions; layout is seeded — the same repo always draws the same map.
• Treemap/matrix polish: cell gaps + rounded corners, styled area headers with color
  chips, readable in-cell numbers (they were dark-on-dark), chip legends instead of prose.
• First paint earns its pixels: the inspector opens with the repo overview (largest
  areas, findings counts, how-to-read) instead of "Pick an item"; engine jargon moved out
  of the masthead into a tooltip; a logomark anchors the header.
• Deterministic demo shots (scripts/screenshot.mjs): staged states (top hotspot
  selected, its area expanded, inspector populated) at 2× retina with fixed framing — every
  committed screenshot (assets/screens/) regenerates from the real report in one command.
  The live demo (docs/demo/) rebuilt on the new template.
