Release v0.4.0

[claude]

[0.4.0] - 2026-07-18

Changed

• Card gains a hairline border in light mode for extra definition (dark mode unchanged)
• Pill-style TabBar now reads as a segmented control: dropped the uppercase/tracked label style, sized up, and added a container border
• Sidebar chrome is now always navy in both light and dark mode; active nav rows carry the orange brand accent and softer rounded corners
• Layout and ContentPane fall back to a cream page background in light mode (was gray)
• ProportionChart gained a legendColumns prop; the legend now lays out in a single non-wrapping row so a trailing item can't become a lone widow, with truncating labels/values
