Changelog

• NEW Semantic Reset CSS (~1KB) — modern reset with box-sizing, list defaults, accessible images, prefers-reduced-motion support. Inlined in <head> when enabled.
• NEW Utility Classes — ~330 Tailwind-inspired utilities (grid, flex, spacing, typography, colors, borders, shadows, etc. + sm:/md:/lg: responsive variants). Frontend inlines ONLY the rules actually used on the page (parses post_content for class names). Builder loads the full set for autocomplete.
