Bumps tailwindcss from 3.4.17 to 4.3.3.

Release notes

Sourced from tailwindcss's releases.

v4.3.3

Fixed

  • Support --watch --poll[=ms] in @tailwindcss/cli when filesystem events are unreliable or unavailable (#20297)
  • Canonicalization: match arbitrary hex colors against theme colors case-insensitively (e.g. bg-[#fff] and bg-[#FFF] → bg-white) (#20298)
  • Prevent Preflight from overriding Firefox's native iframe:focus-visible outline styles (#20292)
  • Ensure theme('colors.foo') in JS plugins resolves correctly when both --color-foo and --color-foo-bar exist (#20299)
  • Ensure fractional opacity modifiers work with named shadow sizes like shadow-sm/12.5, text-shadow-sm/12.5, drop-shadow-sm/12.5, and inset-shadow-sm/12.5 (#20302)
  • Parse selectors like [data-foo]div as two selectors instead of one (#20303)
  • Ensure @tailwindcss/postcss rebuilds when a preprocessor like Sass changes the input CSS without changing the input file on disk (#20310)
  • Ensure CSS nesting is handled even when Lightning CSS isn't run, such as in @tailwindcss/browser and Tailwind Play (#20124)
  • Prevent achromatic theme colors from shifting hue when mixed in polar color spaces like oklch (#20314)
  • Ensure --spacing(0) is optimized to 0px instead of 0 so it remains a <length> when used in calc(…) (#20319)
  • Load @parcel/watcher only when needed in @tailwindcss/cli --watch mode, so one-off builds and --watch --poll work when @parcel/watcher can't be loaded (#20325)
  • Use explicit platform fonts instead of system-ui and ui-sans-serif so CJK text respects the page's lang attribute on Windows (#20318)
  • Prevent @tailwindcss/upgrade from rewriting ignored files when run from a subdirectory (#20329)
  • Ensure earlier @source rules pointing to nested files are scanned when later @source rules point to files in parent folders (#20335)
  • Prevent @tailwindcss/vite from triggering full page reloads when scanned files are processed by Vite but haven't been loaded as modules yet (#20336)

v4.3.2

Fixed

  • Support bare spacing values for auto-rows-* and auto-cols-* utilities (e.g. auto-rows-12 and auto-cols-16) (#20229)
  • Prevent @tailwindcss/cli in --watch mode from crashing on Windows when @source points to a directory that doesn't exist (#20242)
  • Prevent @tailwindcss/vite from crashing in Deno v2.8.x when context.parentURL is not a valid URL (#20245)
  • Ensure @tailwindcss/cli in --watch mode rebuilds when the input CSS file changes in an ignored directory (#20246)
  • Allow @variant rules used in addBase(…) to use custom variants defined later (#20247)
  • Prevent @tailwindcss/vite from crashing during HMR when scanned files or directories are deleted (#20259)
  • Generate font-size instead of color declarations for text-[--spacing(…)] (#20260)
  • Prevent @source patterns from scanning unrelated sibling files and folders (#20263)
  • Extract class candidates adjacent to Template Toolkit delimiters like %]…[% in .tt, .tt2, and .tx files (#20269)
  • Extract class candidates from conditional Maud syntax like p.text-black[condition] (#20269)
  • Prevent @position-try rules from triggering unknown at-rule warnings when optimizing CSS (#20277)
  • Support class suggestions for named opacity modifiers from --opacity theme values (#20287)
  • Prevent type errors in @tailwindcss/postcss when used with newer PostCSS patch releases (#20289)

v4.3.1

Added

  • Add --silent option to suppress output in @tailwindcss/cli (#20100)

Fixed

  • Remove deprecation warnings by using Module#registerHooks instead of Module#register on Node 26+ (#20028)
  • Canonicalization: don't crash when plugin utilities throw for unsupported values (#20052)
  • Allow @apply to be used with CSS mixins (#19427)
  • Ensure not-* correctly negates @container queries, including style(…) queries (#20059)
  • Ensure drop-shadow-* color utilities work with custom shadow values containing calc(…) (#20080)
  • Fix 'Sourcemap is likely to be incorrect' warnings when using @tailwindcss/vite (#20103)
  • Ensure @tailwindcss/webpack can be installed in Rspack projects without requiring webpack as a peer dependency (#20027)

... (truncated)
