Changed

• Secondary filled button now uses NASA Blue (#1C67E3) on all palettes (previously NASA Blue Tint on dark palettes). Passes WCAG AA on all backgrounds.
• Secondary filled button on blue palette automatically renders as outline (transparent background, NASA Blue border) since the filled variant blends into the palette background.
• Table on blue palette now uses the light table variant (white surface) instead of dark.
• Icon button states — hover, active, and disabled styles added for all roles (CTA, secondary, outline, utility, social) across all six palettes.

Improved

• Storybook sidebar — all component stories refactored from single Playground to individual variant stories with focused controls.
• Storybook branding — top-left shows NASA meatball + "HDS Core" text.
• Viewport presets — 7 USWDS breakpoints + TV (deferred) available in toolbar.
• Sidebar sort order — Guidance page always appears first, stories follow export order.
