+review:
+  strengths:
+  - Correct, fully-verified cumulative math (running totals match all displayed labels
+    exactly)
+  - Dotted connector lines and the bold/larger label on the largest single decrease
+    create real visual hierarchy and a clear narrative focal point
+  - rich() mixed-format subtitle is a Makie-idiomatic storytelling touch that ties
+    the headline numbers back into the chart
+  - Theme-adaptive total-bar color (INK) keeps start/end bars distinct from data bars
+    in both themes without introducing an off-palette color
+  - Canvas lands exactly on the 3200x1800 target with no clipping in either render
+  weaknesses:
+  - Total bars (Starting Balance, Net Profit) are colored via the ink/chrome token
+    rather than a dedicated categorical tone; visually distinct and legible, but leans
+    on a chrome color for a data-encoding role
+  - Design Excellence is solid but still close to the documented style-guide skeleton;
+    a bit more customization (e.g. a distinct total-bar hue, subtle bar corner rounding)
+    would push DE-01 further
+  image_description: |-
+    Light render (plot-light.png):
+      Background: Warm off-white, consistent with #FAF8F1
+      Chrome: Title "Quarterly Profit Bridge · waterfall-basic · julia · makie · anyplot.ai", rich-text subtitle, axis ticks/labels, legend (Increase/Decrease/Total) all in dark ink — all clearly readable
+      Data: First series (Increase) is Imprint #009E73 green; Decrease bars use semantic anchor #AE3030 red; Total bars (Starting Balance, Net Profit) are ink/near-black; dotted connector lines link cumulative levels between bars
+      Legibility verdict: PASS
+
+    Dark render (plot-dark.png):
+      Background: Warm near-black, consistent with #1A1A17
+      Chrome: Same title/subtitle/axis/legend elements now rendered in light ink against the dark surface — no dark-on-dark issues; Total bars flip to warm off-white/cream
+      Data: Green (#009E73) and red (#AE3030) data bars are pixel-identical to the light render; only chrome (background, ink, total-bar color) adapts
