review:
17+
strengths:
18+
- 'Pixel-verified: canvas is exactly 3200x1800, and data colors are identical between
19+
light and dark renders — only chrome flips, as required'
20+
- Total labels use genuine typographic hierarchy (rich() bold-oversized value +
21+
smaller/softer unit) rather than uniform text, directly serving the spec's 'eliminate
22+
mental arithmetic' goal
23+
- Clean, idiomatic use of Makie's native stack= keyword on barplot! rather than
24+
manually cumsum-ing segment heights
25+
- ylims! is set last with explicit headroom (max(totals) * 1.16) specifically to
26+
protect label space from being clobbered by autolimits
27+
weaknesses:
28+
- 'Title is disproportionately small: measured at only ~30% of the plot/axis width
29+
(849px / 2814px) against the style guide''s ~50-70% target for this canvas size.
30+
Increase titlesize from 20 toward ~26-28 so the mandated title carries appropriate
31+
visual weight on the 3200x1800 landscape canvas.'
32+
- Y-axis has only two gridlines (5 and 10) across a 0-~13.8 range — slightly sparse
33+
for reading intermediate values off the chart.
34+
image_description: |-
35+
Light render (plot-light.png):
36+
Background: Warm off-white, matches #FAF8F1 target — not pure white, not dark.
37+
Chrome: Title "bar-stacked-labeled · julia · makie · anyplot.ai" centered in dark ink, clearly readable but measured at only ~30% of the plot width (undersized relative to the ~50-70% target). Axis labels ("Quarter" / "Revenue ($M)") and tick labels are dark/soft-ink and legible. Legend at right (Subscriptions/Services/Hardware/Support) is frameless, blends with background, text legible. Total labels ($8.7M, $9.4M, $10.6M, $11.9M) bold and clearly visible above each stack.
38+
Data: Four stacked segments per bar — Subscriptions #009E73 (bottom), Services #C475FD, Hardware #4467A3, Support #BD8233 (top). First series confirmed #009E73.
39+
Legibility verdict: PASS (title is legible but proportionally small — flagged as a VQ-05 weakness, not a legibility failure)
40+
41+
Dark render (plot-dark.png):
42+
Background: Warm near-black, matches #1A1A17 target — not pure black, not light.
43+
Chrome: Title, axis labels, tick labels, legend text, and total labels all flip to light ink (#F0EFE8 / #B8B7B0) and are clearly visible against the dark background. No dark-on-dark failures observed anywhere.
44+
Data: Same four segment colors as the light render, pixel-consistent — only chrome (background/text/grid/legend) changed between themes as required.

Legibility verdict: PASS
