 review:
   strengths:
-  - 'Perfect visual quality: all font sizes explicitly set, both themes render flawlessly
-    with correct backgrounds and chrome'
-  - Correct brand green (#009E73) for the single series in both renders — no palette
-    violations
-  - Clean, well-structured code with proper theme token architecture
-  - Realistic, neutral seasonal temperature dataset with good scale
+  - Theme-adaptive chrome fully implemented with PAGE_BG, INK, INK_SOFT, RULE applied
+    to correct elements
+  - All font sizes explicitly set at correct values (title=24pt, axis=20pt, ticks=16pt)
+  - y-only horizontal grid with no x-grid or minor grid — well-judged minimalism
+  - Monthly temperature dataset is realistic, factually sound, and clearly demonstrates
+    the line plot purpose
+  - Single-series BRAND green consistently correct across both renders
   weaknesses:
-  - Design stops at well-configured default — add geom_area fill under line and refine
-    spine treatment to elevate aesthetic beyond generic output
-  - No visual emphasis on any data feature — add focal point at peak month (month
-    7) via larger marker or annotation
-  - Distinctive letsplot features underutilized — geom_smooth trend overlay or HTML
-    tooltip configuration would improve LM-02
+  - Area fill visible in renders not backed by geom_area() in code — add geom_area(fill=BRAND,
+    alpha=0.15) explicitly to match rendered output
+  - No focal-point emphasis at peak or trough month — larger marker or annotation
+    at July would lift DE-03
+  - LM-02 is low — HTML export uses no letsplot-specific interactive features; layer_tooltips()
+    API would demonstrate library mastery
   image_description: |-
     Light render (plot-light.png):
-      Background: Warm off-white, consistent with #FAF8F1 — not pure white, subtle warmth visible
-      Chrome: Title "line-basic · letsplot · anyplot.ai" in dark ink, top-left; Y-axis label "Temperature (°C)" vertical; X-axis label "Month"; tick labels 1–12 (x) and 4–30 even values (y) in muted dark ink; all clearly readable
-      Data: Single line and points in brand green #009E73; traces sinusoidal seasonal arc from ~4°C (Jan/Dec) to ~29°C peak (Jul); subtle horizontal grid lines; no vertical grid
+      Background: Warm off-white (#FAF8F1) — correct theme surface
+      Chrome: Title "line-basic · letsplot · anyplot.ai" in dark ink top-left; y-axis label "Temperature (°C)" rotated, clearly readable; x-axis label "Month" readable; tick labels 1–12 and y-values all legible in dark ink against off-white
+      Data: Single line and points in #009E73 (BRAND green); area fill under line in matching semi-transparent green; horizontal y-axis grid lines subtle
       Legibility verdict: PASS
 
     Dark render (plot-dark.png):
-      Background: Near-black, consistent with #1A1A17 — warm dark tone, not pure black
-      Chrome: Title, axis labels, and tick labels all rendered in light off-white text — clearly readable against dark surface; no dark-on-dark failures observed
-      Data: Brand green #009E73 line and markers identical in color to light render — data colors unchanged, only chrome flips
+      Background: Near-black (#1A1A17) — correct theme surface
+      Chrome: Title, axis labels, and tick labels all render in light ink tones; readable against dark background; no dark-on-dark failures observed
+      Data: Line, points, and area fill all retain identical #009E73 green — data colors unchanged from light render as required; area fill appears as dark green against the near-black background
