 review:
   strengths:
-  - Excellent geological context with real Grand Canyon formation data and accurate
-    stratigraphy
-  - Strong visual hierarchy with bold formations, italic ages, and red unconformity
-    focal points
-  - Clean declarative Altair code with well-organized layer composition
-  - Good use of age brackets and unconformity markers to organize the geological narrative
-  - Professional color palette with colorblind-safe distinct lithology colors
+  - Excellent spec compliance with all required features including unconformity markers,
+    age brackets, and 5 distinct lithology patterns
+  - Highly realistic data using real Grand Canyon formation names with correct geological
+    ordering
+  - Professional design with custom color palette, typography hierarchy, and clean
+    visual refinement
+  - Red unconformity lines create effective focal points that tell a geological story
+  - Clean, well-organized code with deterministic data
   weaknesses:
-  - Text-based pattern approximations are less distinct than true geological hatching
-    (Altair limitation)
-  - Column width could be wider to better fill the horizontal canvas space
-  - Minor visual crowding near unconformity labels where they overlap with pattern
-    text
-  - Thickness variation in layers is modest (15-25 m range)
-  image_description: 'The plot displays a vertical stratigraphic column of the Grand
-    Canyon sedimentary section spanning Cambrian to Permian periods. Ten geological
-    layers are shown as colored horizontal rectangles stacked vertically with depth
-    increasing downward (0-200 m). Colors used: yellow (Sandstone), gray (Shale),
-    blue (Limestone), purple (Siltstone), orange (Conglomerate). Each layer has text-based
-    pattern overlays approximating geological symbols (dots for sandstone, dashes
-    for shale, squares for limestone, dashes for siltstone, circles for conglomerate).
-    Formation names (Cedar Mesa Fm, Organ Rock Fm, White Rim Fm, De Chelly Fm, Coconino
-    Fm, Hermit Fm, Supai Group, Redwall Fm, Temple Butte Fm, Muav Fm) are labeled
-    to the right in bold. Thickness annotations (15 m, 20 m, 25 m) appear on the far
-    right in italic gray. Age period labels (Permian, Pennsylvanian, Mississippian,
-    Devonian, Cambrian) are on the left with vertical bracket lines. Two red dashed
-    unconformity lines appear at depths 110 and 155 m with labels. The title reads
-    "column-stratigraphic · altair · pyplots.ai" with subtitle "Grand Canyon Sedimentary
-    Section — Cambrian to Permian". A horizontal legend at the bottom shows all 5
-    lithology types. Background is light gray.'
+  - Pattern text overlays could be more prominent — some are subtle against their
+    background colors
+  - Minor crowding near unconformity labels and adjacent formation names at 120m and
+    170m depth
+  - Some canvas space at edges could be better utilized
+  image_description: 'The plot displays a vertical stratigraphic column representing
+    a Grand Canyon sedimentary section spanning Cambrian to Permian periods (0–200m
+    depth). Ten rectangular layers are stacked vertically with depth increasing downward.
+    Each layer is colored by lithology: yellow (Sandstone), gray (Shale), blue (Limestone),
+    purple (Siltstone), and orange (Conglomerate). Text-based pattern overlays differentiate
+    lithologies (dots for sandstone, dashes for shale, squares for limestone, small
+    dashes for siltstone, circles for conglomerate). Formation names (Cedar Mesa Fm,
+    Organ Rock Fm, White Rim Fm, etc.) appear in bold black text to the right of the
+    column. Thickness values in italic gray text appear on the far right. Age period
+    labels (Permian, Pennsylvanian, Mississippian, Devonian, Cambrian) in bold italic
+    dark text appear on the left with vertical bracket lines connecting them to their
+    respective layer ranges. Two red dashed unconformity lines cross the column at
+    120m and 170m with red labels. A horizontal legend at the bottom shows all 5 lithology
+    types. Title reads "column-stratigraphic · altair · pyplots.ai" with subtitle.
