v0.24.4

Added

• Accessibility: layout.css now has a @media (prefers-contrast: more) block — ghost and secondary buttons get explicit borders, cards lose decorative shadows, form inputs get a 2px border, focus rings become thicker (3px, 4px offset), and active nav items get an underline as a colour-independent indicator

Fixed

• Design tokens: corrected --sidebar-width-expanded comment from 1280px+ to 1440px+ to match the actual breakpoint in layout.css
