   - Clean, flat code with clear layout arithmetic that is easy to follow
   - Thoughtful target-node color choice (muted neutrals) creates visual hierarchy

   weaknesses:

     Light render (plot-light.png):
       Background: Warm off-white #FAF8F1 — correct, not pure white
-      Chrome: Title "Energy Flow · sankey-basic · bokeh · anyplot.ai" at 32pt in dark INK — readable; node labels at 22pt in dark INK — all readable; no axis labels (correct for Sankey)
-      Data: Five source nodes (Coal=#009E73, Gas=#D55E00, Nuclear=#0072B2, Hydro=#CC79A7, Solar=#E69F00) with Okabe-Ito canonical order; target nodes in muted neutrals (#5A6A7A, #7A6A8A, #6A7A5A); bezier flow ribbons carry source colors with fill_alpha=0.45; flows look vibrant and translucent on light surface
+      Chrome: Title "Energy Flow · sankey-basic · bokeh · anyplot.ai" at 32pt in dark INK — readable; node labels at 22pt in dark INK — all readable; axes/grid/outline hidden (correct for Sankey)

       Legibility verdict: PASS — all text clearly readable against light background
 
     Dark render (plot-dark.png):
       Background: Near-black #1A1A17 — correct, not pure black
       Chrome: Title and node labels switch to light INK token (#F0EFE8) — all readable; no dark-on-dark text failures detected
-      Data: Source/target node data colors are identical to light render (Okabe-Ito positions unchanged); however fixed fill_alpha=0.45 is not theme-adaptive — flows appear noticeably darker/murkier on dark background making crossing ribbons harder to distinguish; dark-mode target node colors (#5A6A7A, #7A6A8A, #6A7A5A) blend into the dark background reducing target node contrast
+      Data: Source/target node data colors identical to light render (Okabe-Ito positions unchanged); fixed fill_alpha=0.45 is not theme-adaptive — flows appear noticeably darker/murkier on dark background making crossing ribbons harder to distinguish; target node colors (#5A6A7A, #7A6A8A, #6A7A5A) have reduced contrast against near-black background but remain distinguishable
       Legibility verdict: PASS for text; PARTIAL for data elements — flow ribbons have reduced visual impact in dark theme due to non-adaptive alpha
