[dependabot]

Bumps @tailwindcss/postcss from 4.2.4 to 4.3.0.

Release notes

Sourced from @​tailwindcss/postcss's releases.

v4.3.0

Added

• Add @container-size utility (#18901)
• Add scrollbar-{auto,thin,none} utilities for scrollbar-width, and scrollbar-thumb-* / scrollbar-track-* color utilities for scrollbar-color (#19981, #20019)
• Add scrollbar-gutter-* utilities (#20018)
• Add zoom-* utilities (#20020)
• Add tab-* utilities (#20022)
• Allow using @variant with stacked variants (e.g. @variant hover:focus { … }) (#19996)
• Allow using @variant with compound variants (e.g. @variant hover, focus { … }) (#19996)
• Support --default(…) in --value(…) and --modifier(…) for functional @utility definitions (#19989)

Fixed

• Ensure @plugin resolves package JavaScript entries instead of browser CSS entries when using @tailwindcss/vite (#19949)
• Fix relative @import and @plugin paths resolving from the wrong directory when using @tailwindcss/vite (#19965)
• Ensure CSS files containing @variant are processed by @tailwindcss/vite (#19966)
• Resolve imports relative to base when result.opts.from is not provided when using @tailwindcss/postcss (#19980)
• Canonicalization: preserve significant _ whitespace in arbitrary values (#19986)
• Canonicalization: add parentheses when removing whitespace from arbitrary values would hurt readability (e.g. w-[calc(100%---spacing(60))] → w-[calc(100%-(--spacing(60)))]) (#19986)
• Canonicalization: preserve the original unit in arbitrary values instead of normalizing to base units (e.g. -mt-[20in] → mt-[-20in], not mt-[-1920px]) (#19988)
• Canonicalization: migrate arbitrary :has() variants from [&:has(…)] to has-[…] (#19991)
• Upgrade: don’t migrate inline style attributes (e.g. style="flex-grow: 1" → style="flex-grow: 1", not style="grow: 1") (#19918)
• Allow multiple @utility definitions with the same name but different value types (#19777)
• Export missing PluginWithConfig type from tailwindcss/plugin to fix errors when inferring plugin config types (#19707)
• Ensure start and end legacy utilities without values do not generate CSS (#20003)
• Ensure --value(…) is required in functional @utility definitions (#20005)
• Canonicalization: preserve required whitespace around operators in negated arbitrary values (e.g. -left-[(var(--a)+var(--b))]) (#20011)

In `@playground/package.json`:
- Line 37: The package version for tailwindcss is out of sync with
`@tailwindcss/postcss` (which is ^4.3.0); update the tailwindcss entry in
package.json (the "tailwindcss" dependency) from ^4.2.4 to ^4.3.0 so both
packages match the v4.3.0 release and avoid compatibility issues with the v4
architecture.
