tegwick 53abbaf68f CB-WP-0012-T01: survey the render port — and find AM-4a mis-instrumented
Measured with dep-weight.py's own method so the numbers subtract.
Marginal cost against the 23-crate base graph, not headline size:

  egui+eframe          2,782,849   742x headroom
  wgpu+winit           1,741,979   465x
  softbuffer+tiny-skia 1,147,081   306x
  ratatui+crossterm    1,067,013   285x
  macroquad              480,501   128x
  HTML/SVG emission            0     0x

ratatui costing more than macroquad is the surprise: rustix pulls
linux-raw-sys at 479,901 lines.

Separately, AM-4a counts proc-macro crates that never reach a binary:
89,048 lines, 36.2% of the shipped-runtime figure, syn alone 66,916.
Real headroom is 92,798, not the 3,750 this repo has been citing.

The recommendation is unchanged by that correction — macroquad is 5.2x
over even at 92,798 — which is the only condition under which a survey
may propose correcting a number in its own favour. The metric fix is
filed separately, not bundled with the decision it unblocks.
