+review:
+  strengths:
+  - Correct Imprint palette with brand green first series, verified identical across
+    both themes
+  - Theme-adaptive chrome fully correct in both light and dark renders — no legibility
+    failures
+  - 'Sound engineering for a library gap: Makie has no native swarm/beeswarm geom,
+    so the greedy nearest-free-slot collision algorithm is a legitimate, well-commented
+    solution rather than a workaround'
+  - Subtitle explicitly ties the data story to the visual (bolded median line for
+    the leading department)
+  - Realistic, well-varied data across all four departments (different means, spreads,
+    and outliers)
+  weaknesses:
+  - LM-02 is low — the implementation doesn't lean on anything distinctive to Makie
+    beyond colorant/RGBAf tokens; consider a Makie-specific touch (e.g. a Legend block,
+    a custom recipe, or GeometryBasics-based marker shapes) to raise library mastery
+  - Busiest swarm bands (Sales ~76-81, Marketing ~74-79) read slightly dense — a marginal
+    reduction in markersize or increase in step_x/min_dist_y would improve point-level
+    visibility without changing the overall shape
+  - DE-01/DE-02 are solid but not yet publication-tier — a touch more restraint on
+    y-axis padding and a slightly stronger visual differentiator for the winning department
+    (beyond line-width) would push this further
+  image_description: |-
+    Light render (plot-light.png):
+      Background: Warm off-white, consistent with #FAF8F1 — not pure white, not dark.
+      Chrome: Bold centered title "swarm-basic · julia · makie · anyplot.ai" in dark ink; soft-ink subtitle "Support leads with the highest median score (83)"; axis titles "Department" / "Performance Score (0-100)" and tick labels all in dark/soft-ink tones, fully readable. Subtle horizontal-only gridlines every 10 units.
+      Data: Four beeswarm columns — Engineering=#009E73 (first series, brand green confirmed), Sales=#C475FD lavender, Support=#4467A3 blue, Marketing=#BD8233 ochre. Solid median line per department, bolder for Support (the leader).
+      Legibility verdict: PASS
+
+    Dark render (plot-dark.png):
+      Background: Warm near-black, consistent with #1A1A17 — not pure black, not light.
+      Chrome: Title, subtitle, axis titles, and tick labels flip to light/soft-light ink and remain fully legible; gridlines and median lines switch to light tone appropriate for dark surface. No dark-on-dark failures found.
+      Data: Colors identical to light render (#009E73/#C475FD/#4467A3/#BD8233) — only chrome flipped, confirmed by direct comparison.
