 review:
   strengths:
-  - Perfect text legibility in both light and dark themes with theme-adaptive colors
-    throughout
-  - Correct and strict Okabe-Ito palette adherence with brand green (#009E73) as first
-    series
-  - Clean, minimal code structure with no unnecessary complexity; fully reproducible
-  - Proper canvas sizing for symmetric plots (3600x3600 px final) with correct export
-    scaling
-  - 'Background colors exactly match spec (#FAF8F1 light, #1A1A17 dark); no pure white/black'
-  - Realistic monsoon wind pattern with accurate meteorological context
-  - Bars have white edges and alpha=0.85 for visual definition
+  - Proper polar coordinate system implementation showing clear directional distribution
+  - Theme-adaptive design correctly applies light (#FAF8F1 background, dark ink) and
+    dark (#1A1A17 background, light ink) tokens in both renders
+  - Excellent text legibility in both themes with no contrast issues—all compass directions,
+    title, and axis labels clearly readable
+  - Clean, idiomatic lets_plot code using coord_polar and ggplot grammar patterns
+    effectively
+  - Correct Okabe-Ito palette integration with 8 direction colors, maintains color
+    consistency across themes
+  - Wind rose format effectively communicates frequency distribution with SW dominance
+    visually apparent
+  - White bar edges provide subtle definition without clutter
   weaknesses:
-  - 'Design Excellence is low: implementation is clean but lacks distinctive aesthetic
-    choices beyond the minimal theme'
-  - 'Library Mastery limited: uses core letsplot features correctly but doesn''t showcase
-    library-specific capabilities or advanced customization'
-  - 'Visual hierarchy is functional but not intentional: plot communicates data clearly
-    but doesn''t emphasize key patterns (SW dominance) through color, size, or position
-    emphasis'
+  - 'Design Excellence could be enhanced: grid styling is functional but could use
+    more sophisticated visual refinement (e.g., asymmetric line weights or selective
+    grid emphasis)'
+  - Visual hierarchy of dominant direction (SW=35) could be strengthened through size
+    emphasis, brightness variation, or strategic color placement to guide viewer attention

     Light render (plot-light.png):
-      Background: Warm off-white (#FAF8F1) - matches spec exactly
-      Chrome: Title "polar-bar · letsplot · anyplot.ai" in dark INK color (#1A1A17); Y-axis labeled "Frequency (%)" in INK; tick labels (5, 10, 15, 20, 25, 30, 35) and direction labels (N, NE, E, SE, S, SW, W, NW) in INK_SOFT gray (#4A4A44). All text is clearly readable against light background.
-      Data: 8 bars radiating outward using Okabe-Ito colors in order: N (#009E73 green), NE (#D55E00 orange), E (#0072B2 blue), SE (#CC79A7 purple), S (#E69F00 gold), SW (#56B4E9 sky blue), W (#F0E442 yellow), NW (#1A1A1A dark neutral). Bars have white edges for definition. Grid circles are subtle but visible. Proportions correct: SW largest (35), S second (28), others smaller (3-12).
-      Legibility verdict: PASS - all elements visible, no light-on-light failures, excellent contrast
+      Background: Warm off-white (#FAF8F1) with subtle grid lines, correctly theme-adapted.
+      Chrome: Title "polar-bar · letsplot · anyplot.ai" is bold and prominent (24pt, dark text #1A1A17). Y-axis label "Frequency (%)" (20pt, dark text). Compass directions (N, NE, E, SE, S, SW, W, NW) positioned around circle are all readable at 16pt. All text has strong contrast.
+      Data: Bars radiate from center with Okabe-Ito palette colors. SW bar (freq=35) is prominent blue, S (freq=28) is yellow-gold, SE (freq=12) is magenta/purple. Smaller bars (freq=3-6) use remaining palette colors. White edges on bars provide clean definition. Colors are from Okabe-Ito palette as specified.
+      Legibility verdict: PASS - All text and data elements clearly distinguishable against light background. No light-on-light failures.
 
     Dark render (plot-dark.png):
-      Background: Warm near-black (#1A1A17) - matches spec exactly
-      Chrome: Title in light INK color (#F0EFE8); Y-axis label and tick labels in light INK_SOFT (#B8B7B0). All text is clearly readable against dark background with good contrast.
-      Data: Colors identical to light render (Okabe-Ito positions 1-7 constant). Neutral bar (NW) correctly adapts to #E8E8E0 (light off-white) for visibility. Grid circles remain subtle. No dark-on-dark failures - all text sufficiently light and all data bars sufficiently distinct.
-      Legibility verdict: PASS - no dark-on-dark failures, excellent theme adaptation, all elements readable
+      Background: Warm near-black (#1A1A17) with visible grid lines, correctly theme-adapted.
+      Chrome: Title clearly visible in light text (#F0EFE8). Y-axis label readable in same light tone. Compass directions have excellent contrast against dark background. All chrome elements use proper dark-theme tokens.
+      Data: Bar colors are identical to light render (data colors should not change with theme—only chrome flips). White bar edges remain visible and effective. Grid lines visible at appropriate contrast level.
+      Legibility verdict: PASS - No dark-on-dark failures. All text elements have strong contrast. Data visualization quality maintained perfectly between themes. Both renders demonstrate proper theme adaptation with only chrome elements changing color.
