Bars have subtle rounded corners. Spacing between groups is appropriate for visual separation. Data density is ideal (4 quarters × 3 products = 12 bars total). + Legibility verdict: PASS - All text is readable. No text-on-text collisions. Strong contrast between chrome and background. Dark render (plot-dark.png): - Background: Warm near-black #1A1A17 as specified - Chrome: Title and axis labels render in light text (INK_SOFT color), tick labels are light, legend text is light—all readable against dark background, no dark-on-dark failures - Data: Bar colors remain identical to light render (#009E73, #D55E00, #0072B2)—confirms proper theme separation, only chrome flips - Legend: Light text on dark background (#242420 frame), clearly readable - Grid: Light-colored grid at 10% opacity, subtle and visible - Legibility verdict: PASS—all text readable, no dark-on-dark failures, strong contrast, color identity preserved across themes + Background: Warm near-black #1A1A17 with subtle grid lines.

Bars are clearly visible and distinguishable from dark background. Rounded corners maintain visual identity. + Legibility verdict: PASS - No dark-on-dark issues. All elements properly adapted for dark theme. Brand green (#009E73) is vibrant and distinct. Both renders are theme-correct. + + Summary: Both renders pass legibility checks. Chrome adapts properly between themes (only background/text colors flip). Data colors remain constant.
