+review:
+  strengths:
+  - Proper theme-adaptive design with correct color token usage
+  - OHLC bars correctly implemented with vertical high-low lines and open-close ticks
+  - Excellent legibility in both light and dark themes
+  - Data colors consistent across themes (Okabe-Ito compliant)
+  - Smart opacity variation by volatility adds visual sophistication
+  - Clean, idiomatic ggplot2 code with proper geom_segment usage
+  - Reproducible data generation with set.seed(42)
+  - 7-day moving average provides useful context line
+  weaknesses:
+  - Design is functional but lacks distinctive polish - relies heavily on theme_minimal
+    defaults
+  - No visual hierarchy or emphasis technique to create focal point
+  - Panel border present but spines not explicitly addressed (no removal/customization)
+  - Moving average styling is subtle but could benefit from more design intentionality
+  image_description: |-
+    Light render (plot-light.png):
+      Background: Warm off-white (#FAF8F1) with subtle border in BORDER_COL
+      Chrome: Title "ohlc-bar · ggplot2 · anyplot.ai" in bold dark text (24pt, #1A1A17). X-axis label "Date" and Y-axis label "Price ($)" in bold dark (20pt). Tick labels in soft dark (#4A4A44, 16pt) with date rotation at 45°. All text clearly readable against light surface.
+      Data: OHLC bars correctly rendered with green (#009E73) for up-bars, orange (#D55E00) for down-bars. Vertical lines show high-low range, horizontal ticks left (open) and right (close). Opacity variation shows volatility. Dotted trend line in INK_SOFT shows 7-day moving average. Y-axis grid subtle and appropriate.
+      Legibility verdict: PASS - All text readable, excellent contrast, no overlaps, proper theme mapping.
+
+    Dark render (plot-dark.png):
+      Background: Warm near-black (#1A1A17) with appropriate border
+      Chrome: Title in light text (24pt, #F0EFE8), clearly visible. X and Y axis labels in light text (20pt, #F0EFE8). Tick labels in light gray (#B8B7B0, 16pt), all readable. No dark-on-dark failures detected.
+      Data: OHLC bars with identical data colors to light render - green (#009E73) and orange (#D55E00) preserved perfectly. Vertical and horizontal segments properly colored and visible. Opacity variation maintained. Dotted trend line visible. Grid properly themed.
+      Legibility verdict: PASS - All text readable, excellent contrast on dark surface, proper color preservation, no chrome failures.
