Tailwind CSS v4.3: CSS-first config, renamed utilities, and what changed in 4.1-4.3

Tailwind CSS is on v4.3.x (4.3.3, 2026-07-16). v4 is configured in CSS (`@import "tailwindcss"`, `@theme`), not `tailwind.config.js`; several utilities were renamed and defaults changed. 4.2/4.3 added logical-property utilities and deprecated `start-*`/`end-*`.
