 review:
   strengths:
-  - Excellent text legibility with explicitly sized fonts (title 28px, labels 22px,
-    ticks 18px)
-  - Well-formatted title matching spec requirement (line-timeseries · pygal · anyplot.ai)
-  - Realistic and plausible data (stock prices with volatility over 365 days)
-  - Clean, deterministic code with proper seeding (random.seed(42))
-  - Good layout and margins (100px margin, well-balanced)
+  - 'Perfect visual quality: all text explicitly sized, readable in both themes, no
+    overlap, proper palette compliance'
+  - Correct time-series implementation with realistic stock price data and meaningful
+    date range (full year)
+  - 'Theme adaptation is flawless: no dark-on-dark or light-on-light failures in either
+    render'
+  - Clean, reproducible code following project guidelines with deterministic seed
+  - Intelligent x-axis label formatting (month-year with 45-degree rotation prevents
+    overlap)
   weaknesses:
-  - 'CRITICAL: Data line color inconsistent between light and dark renders—light render
-    shows pale/grayish line, dark render shows greenish line; they should be identical
-    (#009E73). Suggests Style object colors not applied correctly or rendering issue
-    with pygal.'
-  - Low aesthetic sophistication (DE-01=4/8)—uses library defaults without custom
-    design choices
-  - Minimal visual refinement (DE-02=2/6)—no spine customization, basic grid, default
-    styling
-  - No visual storytelling emphasis (DE-03=2/6)—uptrend is visible but no visual hierarchy
-    highlights the insight
-  - Generic library usage (LM-02=1/5)—could leverage more pygal-specific features
+  - 'Design excellence is conservative: correct but no distinctive aesthetic choices
+    beyond well-configured defaults'
+  - 'Visual refinement could improve: spines not removed, grid not customized beyond
+    default appearance'
+  - 'Data storytelling is minimal: no visual emphasis or hierarchy to highlight the
+    upward trend or volatility pattern'
+  - 'Library mastery is competent but not exceptional: could leverage more pygal-specific
+    interactive or styling features'
   image_description: |-
     Light render (plot-light.png):
-      Background: Warm off-white (#FAF8F1) - correct
-      Chrome: Title "line-timeseries · pygal · anyplot.ai" clearly visible; X-axis "Date", Y-axis "Stock Price (USD)" with units; date labels rotated 45° (Jan 2024 through Dec 2024); price range ~100-210; all text readable (PASS)
-      Data: Single line series showing stock price over 365 days - CRITICAL ISSUE: line appears very pale and grayish, barely visible, NOT the expected #009E73 bluish-green color
-      Grid: Subtle grid lines on both axes visible and appropriate
-      Legend: "ACME Corp Stock" shown at bottom left
-      Legibility verdict: FAIL - Data line color is wrong (appears pale/grayish instead of medium-saturated bluish-green #009E73). Text legibility is good, but the data element itself fails palette compliance.
+      Background: Warm off-white (#FAF8F1) - correct and visually appealing
+      Chrome: Title "line-timeseries · pygal · anyplot.ai", axis labels "Date" and "Stock Price (USD)", legend "ACME Corp Stock" all rendered in dark text, clearly visible and readable against light background
+      Data: Line in brand green (#009E73) showing stock price over 365 days; x-axis displays month-year labels at 45 degrees for readability; y-axis shows price range 100-160 USD; grid lines subtle but visible
+      Legibility verdict: PASS - All text readable, no collisions, data clearly distinguishable from background
 
     Dark render (plot-dark.png):
-      Background: Warm near-black (#1A1A17) - correct
-      Chrome: Title visible; axis labels visible in light text; date labels rotated, clearly readable; all text is light-colored and readable against dark background (PASS on chrome legibility)
-      Data: Line appears greenish/teal, which is closer to expected #009E73 but DIFFERS from light render appearance. The colors MUST be identical between renders—only chrome should flip.
-      Grid: Subtle grid lines visible on both axes
-      Legend: "ACME Corp Stock" shown
-      Legibility verdict: FAIL - Data line color differs from light render. While the line is visible and readable, the color inconsistency across themes violates the style guide requirement that data colors remain identical between light/dark renders. This is a critical palette compliance failure.
+      Background: Warm near-black (#1A1A17) - correct and consistent with light render
+      Chrome: All text elements (title, labels, legend) rendered in light colors, fully readable against dark background; no dark-on-dark failures detected
+      Data: Line identical to light render in #009E73 green - perfect theme consistency; grid lines equally subtle; legend and axis labels properly light-colored
+      Legibility verdict: PASS - All text readable, no theme-adaptation failures, data colors identical to light render (only chrome adapted)
