 review:
   strengths:
-  - Excellent use of seaborn jointplot for this plot type, which is specifically designed
-    for scatter plots with marginal distributions
-  - Good visual balance with appropriate font sizes using sns.set_context(talk, font_scale=1.4)
-  - Effective combination of histograms and KDE curves in marginal plots as suggested
-    by the spec
-  - Appropriate transparency (alpha=0.65) and marker size for 200 data points with
-    white edge for visibility
-  - Correct title format following pyplots.ai conventions
+  - Correct plot type with proper layout (scatter + marginal histograms + KDE curves)
+  - 'Excellent visual quality: readable in both light and dark themes, no overlapping
+    elements'
+  - Idiomatic use of seaborn's jointplot API with thoughtful customization (alpha,
+    KDE, grid styling)
+  - 'Strong data storytelling: correlated Temperature-IceCreamSales data clearly shows
+    positive relationship'
+  - 'Perfect specification compliance: correct title format, proper data mapping,
+    all required features present'
+  - Clean code structure with reproducible random seed
   weaknesses:
-  - Axis labels are generic (X Value, Y Value) instead of domain-specific labels with
-    units
-  - Data scenario is generic rather than representing a real-world use case
-  - Grid uses dashed style which is slightly more prominent than subtle solid gridlines
-  image_description: The plot displays a scatter plot with marginal distributions
-    using seaborn's jointplot. The central scatter plot shows 200 blue points (#306998)
-    with moderate transparency (alpha 0.65) and white edges. There is a clear positive
-    correlation visible in the data. The top marginal shows a histogram with ~25 bins
-    and an overlaid KDE curve for the X variable distribution. The right marginal
-    shows a horizontal histogram with KDE for the Y variable distribution. Both marginal
-    histograms use the same blue color with alpha 0.7. The title "scatter-marginal
-    · seaborn · pyplots.ai" appears at the top. Axis labels show "X Value" and "Y
-    Value" with a subtle dashed grid. The overall layout is square (~1:1 aspect ratio)
-    which is appropriate for jointplots.
+  - 'CQ-05: Code saves to bare ''plot.png'' instead of theme-specific ''plot-{THEME}.png'';
+    no ANYPLOT_THEME environment variable checking in the code (output is correct
+    via pipeline wrapper, but code itself is missing theme-adaptive implementation)'
+  - 'VQ-01: Font sizes are adequate but could be slightly larger for the 4800x2700px
+    canvas for even better prominence'
+  - 'DE-01: Design is sophisticated but fairly standard seaborn jointplot styling
+    - could use more intentional aesthetic choices (custom palette beyond defaults,
+    unique visual hierarchy)'
+  image_description: |-
+    Light render (plot-light.png):
+      Background: Warm off-white (#FAF8F1) - correct
+      Chrome: Title "scatter-marginal · seaborn · anyplot.ai" is clearly visible in dark text. Axis labels "Temperature (°C)" and "Ice Cream Sales ($)" are readable and descriptive. Tick labels are well-sized and contrast well against the light background.
+      Data: Central scatter plot uses teal/green color (#009E73 - Okabe-Ito brand color) with good alpha transparency (0.65) to reveal overlapping points. Top marginal histogram and right marginal histogram show KDE curves overlaid, using matching color with slightly different alpha (0.7). Grid lines are subtle but visible.
+      Legibility verdict: PASS - all text is clearly readable, no dark-on-light failures
+
+    Dark render (plot-dark.png):
+      Background: Warm near-black (#1A1A17) - correct
+      Chrome: Title is in light/white text on dark background, clearly visible. Axis labels are light-colored and readable. Tick labels are light and well-defined against the dark background. No dark-on-dark failures detected.
+      Data: Scatter plot data color is IDENTICAL to light render (#009E73) - excellent. Top and right marginal histograms with KDE curves maintain the same brand green color, showing excellent theme consistency. Grid lines are subtle but visible in both themes. All chrome elements (text, spines, grid) are correctly theme-adapted from the light render.
+      Legibility verdict: PASS - all text is clearly readable in dark theme, excellent dark-on-light contrast, no theme-adaptation failures
