 review:
   strengths:
-  - Excellent realistic data scenario (national energy flow — the canonical Sankey
-    use case)
-  - Good two-stage connected Sankey using matplotlib native prior/connect API
-  - Energy balance verified with assert — good correctness practice
-  - Both renders show visually appealing clean layout with proper axis removal
-  - Clear visual hierarchy between source and distribution stages via two-color scheme
-  - TWh values on node labels add quantitative context without clutter
+  - Excellent use of matplotlib.sankey.Sankey multi-diagram connection (prior/connect)
+    — idiomatic and expressive
+  - Energy-balance assertion makes data self-validating and shows good engineering
+    discipline
+  - Clean canvas via ax.axis(off) with large bold labels — clear and readable
+  - Two-color staging creates natural source-to-end-use visual narrative with good
+    proportions
+  - Neutral, realistic energy domain with plausible TWh values
   weaknesses:
-  - 'Critical: Code uses #306998 (Python Blue) and #FFD43B (Python Yellow) instead
-    of Okabe-Ito palette (#009E73 and #D55E00) — VQ-07 hard fail'
-  - 'Critical: No ANYPLOT_THEME environment variable handling — no theme-adaptive
-    backgrounds, text colors, or chrome; saves as plot.png not plot-{THEME}.png'
-  - 'Critical: Code has pyplots.ai in the title instead of anyplot.ai'
-  - Title has extra National Energy Flow prefix — format must be {spec-id} · {library}
-    · anyplot.ai
-  - 'Subtitle uses hardcoded color #555555 which will not adapt to dark theme (should
-    use INK_MUTED token)'
-  - No legend creation code despite legend appearing in rendered images (images appear
-    to be from a different code version)
+  - 'CRITICAL: facecolor=#306998 (Python Blue) and facecolor=#FFD43B (yellow) — must
+    use Okabe-Ito #009E73 for first hub and #D55E00 for second hub'
+  - 'CRITICAL: No theme adaptation — must add os.getenv(ANYPLOT_THEME) block with
+    PAGE_BG/INK/INK_MUTED tokens; set figure/axes facecolor, text colors via tokens'
+  - 'CRITICAL: Output saved as plot.png — must be f"plot-{THEME}.png" for pipeline
+    to find it'
+  - 'IMPORTANT: Title is National Energy Flow · sankey-basic · matplotlib · pyplots.ai
+    — must be exactly sankey-basic · matplotlib · anyplot.ai'
+  - 'Annotation color #555555 hardcoded — use INK_MUTED token for dark-mode readability'
   image_description: |-
     Light render (plot-light.png):
-      Background: Warm off-white (~#FAF8F1) — correct theme surface, NOT pure white
-      Chrome: Title "National Energy Flow · sankey-basic · matplotlib · anyplot.ai" in dark text, clearly readable; node labels bold dark text; subtitle italic in medium gray; legend with dark text labels — all readable against light background
-      Data: Left Sankey in teal-green (~#009E73 range), right Sankey in orange-brown (~#D55E00 range); flow widths proportional to TWh values; Coal (120 TWh) largest, Transport (20 TWh) smallest but still distinct
-      Legibility verdict: PASS — all text clearly readable against warm off-white background
+      Background: Warm off-white (~#FAF8F1) — correct theme surface, not pure white
+      Chrome: Title "sankey-basic · matplotlib · anyplot.ai" large/bold/readable; embedded flow labels (18pt bold) fully legible; subtle italic annotation at bottom visible
+      Data: Left hub teal-green (~#009E73) covering Coal/Gas/Nuclear/Renewables/Losses; right hub orange-brown (~#D55E00) covering Residential/Commercial/Industrial/Transport; two-color approach clearly distinguishes source vs end-use
+      Legibility verdict: PASS
 
     Dark render (plot-dark.png):
-      Background: Warm near-black (~#1A1A17) — correct theme surface, NOT pure black
-      Chrome: Title in light-colored text, clearly readable; node labels in light text against dark background; subtitle in lighter gray; legend with light text and dark-elevated box fill — all readable against dark background; NO dark-on-dark failures observed
-      Data: Colors identical to light render — same teal-green and orange-brown (only chrome flips, data colors stable); brand green remains visible on dark surface
-      Legibility verdict: PASS — all text clearly readable against near-black background
+      Background: Dark near-black (~#1A1A17) — correct dark surface, not pure black
+      Chrome: Title and flow labels all clearly readable as light text; annotation visible; no dark-on-dark failures observed; text and background contrast is good
+      Data: Colors identical to light render — same teal-green and orange-brown Sankey flows; only chrome (background) flips
+      Legibility verdict: PASS
 
-    CRITICAL DISCREPANCY NOTE: The rendered images do NOT match the current code. The code uses #306998 (Python Blue) and #FFD43B (Python Yellow) with no ANYPLOT_THEME handling and saves as plot.png. The images appear to have been generated from a different (earlier, fixed) version of the code. The current code file would produce incorrect output (wrong colors, no theme adaptation, wrong filename) if run now.
+    NOTE: Code-image discrepancy detected. Current code uses facecolor="#306998" (Python Blue) and "#FFD43B" (yellow), which do NOT match the teal/orange seen in the images. Code also lacks theme adaptation and saves to plot.png not plot-{THEME}.png. Images appear stale from a previous run. VQ-07 and CQ-05 scored against the code.
