Auto-compute contrast text color for accent backgrounds

Add --primary-contrast CSS variable that auto-switches between white and
dark text based on accent color luminance (WCAG relative luminance).
Replace all hardcoded #fff/white on primary-color backgrounds with
var(--primary-contrast) so light accent colors like yellow remain readable.
