 review:
   strengths:
-  - Perfect spec compliance with all required features (endpoint labels, directional
-    coloring, time-point axis labels)
-  - 'Excellent code quality: flat KISS structure, deterministic data, all explicit
-    font sizes set for 4800x2700px'
-  - Theme-adaptive chrome implemented correctly per letsplot guide; both renders pass
-    legibility checks
-  - 'Directional color coding with Okabe-Ito #009E73/#D55E00 creates instant visual
-    hierarchy'
+  - Excellent spec compliance — all slopegraph requirements satisfied with correct
+    title format
+  - Strong storytelling via top-3 mover emphasis (differential line weight + alpha)
+    creates a clear focal story
+  - Proper Okabe-Ito palette with full theme-adaptive chrome; both light and dark
+    renders pass the readability check
+  - 'Perfect code quality: deterministic, clean, idiomatic letsplot usage'
+  - Genuine use of layer_tooltips() showcases letsplot's interactive differentiation
   weaknesses:
-  - 'Label crowding on right side: six products (B, C, I, H, A, D) fall in a tight
-    55-unit band producing near-overlap — fix by adding value amounts to endpoint
-    labels and extending y-limits'
-  - Generic entity names Product A through J reduce data authenticity — replace with
-    real product category names from a recognizable industry
-  - 'No data storytelling emphasis: top mover (Product G +40) and biggest decline
-    (Product J -30) not visually distinguished — use size or alpha variation to highlight
-    top 2-3 movers'
+  - Label crowding on both sides (especially left, mid-range values) causes overlap
+    where 4-5 entities cluster near similar y-values
+  - geom_text label size=10 renders slightly small at 4800x2700 px; size 12-13 would
+    improve legibility

     Light render (plot-light.png):
-      Background: Warm off-white (#FAF8F1) — correct theme surface, not pure white
-      Chrome: Title "slope-basic · letsplot · anyplot.ai" in dark ink (#1A1A17) — clearly readable. Y-axis label "Sales ($K)" in dark ink. X-axis tick labels "Q1 Sales ($K)" / "Q4 Sales ($K)" in INK_SOFT (#4A4A44). Tick labels on y-axis in INK_SOFT. Legend box with elevated background.
-      Data: Green (#009E73) lines/points for increasing products; orange (#D55E00) for decreasing. 10 slope lines clearly visible. Entity labels at both endpoints.
-      Legibility verdict: PASS — all text readable; minor label crowding on right side (6 labels in 55-unit band) but not severe overlap
+      Background: Warm off-white #FAF8F1 — correct light theme surface.
+      Chrome: Title "slope-basic · letsplot · anyplot.ai" in dark ink (#1A1A17), clearly readable. Y-axis label "Sales ($K)" and x-axis tick labels "Q1 Sales ($K)"/"Q4 Sales ($K)" in dark soft ink — all readable. Legend on right with "Change" header and green/orange entries, styled with elevated background.
+      Data: Green (#009E73) segments for increases, orange (#D55E00) for decreases. Top-3 movers (Cameras, Smartphones, Laptops) emphasized with bold lines (size=3.5, alpha=1.0); background lines dimmed (alpha=0.40). Endpoint labels on both sides with entity name + value.
+      Legibility verdict: PASS — all chrome text readable. Minor label overlap in mid-range ($80K-$120K) band.
 
     Dark render (plot-dark.png):
-      Background: Warm near-black (#1A1A17) — correct dark theme surface, not pure black
-      Chrome: Title and axis labels rendered in light ink (#F0EFE8 / #B8B7B0) — all clearly readable against dark background. No dark-on-dark failures observed. Legend box uses elevated dark background (#242420).
-      Data: Colors are identical to light render — green (#009E73) for increases, orange (#D55E00) for decreases. Theme-stable palette confirmed.
-      Legibility verdict: PASS — all text readable in dark theme; same label crowding as light render
+      Background: Near-black #1A1A17 — correct dark theme surface.
+      Chrome: Title, axis labels, tick labels, and legend text all shift to light ink (#F0EFE8/#B8B7B0). All text readable against dark background. No dark-on-dark failures observed. Legend background uses elevated dark surface #242420.
+      Data: Data colors identical to light render — green #009E73 for increases, orange #D55E00 for decreases. Same visual hierarchy (bold top movers vs. dimmed background lines).
+      Legibility verdict: PASS — theme-adaptive chrome successfully applied to all elements.
