 review:
   strengths:
   - Excellent spec compliance with all required features including 5 distinct lithology
-    patterns, formation labels, age labels, depth scale, and unconformity wavy line
-  - Domain-appropriate data with realistic geological formation names, ages, and sedimentary
-    sequence
-  - Good use of pattern overlays to approximate standard geological symbols
-  - Clean procedural code structure with deterministic data
-  - Interactive tooltips showing lithology, depth, thickness, formation, and age details
+    patterns, formation names, age labels with brackets, and wavy unconformity line
+  - Realistic geologically plausible data with proper formation names and age progression
+  - Good use of lets-plot distinctive features (layer_tooltips, flavor_high_contrast_light)
+  - Clean deterministic code with appropriate complexity for pattern generation
+  - Strong visual hierarchy with red unconformity as focal point
   weaknesses:
-  - Unused boundaries_df variable (dead code at lines 169-172)
-  - Pattern overlays are somewhat subtle due to low alpha values reducing geological
-    readability
-  - Formation label font size (12) and age label font size (13) are noticeably smaller
-    than axis text (16)
-  - Limited use of lets-plot-specific distinctive features
-  image_description: 'The plot shows a vertical stratigraphic column spanning 0-260
-    meters depth with 10 geological layers. The y-axis is labeled "Depth (m)" increasing
-    downward. Each layer is a colored rectangle: Sandstone in yellow (#F5D76E), Shale
-    in gray (#7A7A7A), Limestone in blue (#6BAED6), Siltstone in tan/brown (#C4956A),
-    and Conglomerate in pink/red (#D4726A). Each lithology has distinctive pattern
-    overlays - stipple dots for sandstone, horizontal dashes for shale, brick pattern
-    (horizontal + offset vertical lines) for limestone, tilted dashes for siltstone,
-    and open circles for conglomerate. Formation names (e.g., "Basal Sand Fm", "Dark
-    Shale Mbr") are labeled on the right side. Geological age labels (Triassic, Jurassic,
-    Cretaceous, Paleogene) appear in italics on the left with bracket indicators.
-    Dashed horizontal lines mark age boundaries at 35m and 195m, and a red wavy line
-    at ~110m marks an unconformity at the Jurassic/Cretaceous boundary. A legend at
-    bottom shows all 5 lithology types. Title reads "column-stratigraphic · letsplot
-    · pyplots.ai". White background with subtle horizontal grid lines.'
+  - Some lithology patterns (siltstone dashes, sandstone stipple) could be denser
+    for better visual distinction
+  - Layout has some wasted horizontal space due to wide x-axis range
+  - Design excellence could be higher with more refined boundary styling
+  image_description: 'The plot displays a vertical stratigraphic column spanning 0-260m
+    depth (increasing downward). Ten geological layers are shown as colored rectangular
+    blocks: yellow (Sandstone), gray (Shale), blue (Limestone), tan/brown (Siltstone),
+    and pink/red (Conglomerate). Each lithology type has a distinctive overlay pattern
+    - stipple dots for sandstone, horizontal dashes for shale, brick pattern (horizontal
+    + offset vertical lines) for limestone, tilted short dashes for siltstone, and
+    open circles for conglomerate. Formation names (e.g., "Basal Sand Fm", "Reef Limestone
+    Fm") appear to the right of each layer. Age labels ("Triassic", "Jurassic", "Cretaceous",
+    "Paleogene") in italics with bracket indicators appear on the left side. A red
+    wavy unconformity line at approximately 110m depth is labeled "Unconformity" in
+    bold red text. Dashed horizontal lines mark non-unconformity age boundaries at
+    35m and 195m. The legend at the bottom shows all 5 lithology types with their
+    color swatches. The title reads "column-stratigraphic · letsplot · pyplots.ai"
+    in bold at the top. The Y-axis is labeled "Depth (m)" with tick marks every 20m.'
