[dependabot]

Bumps tailwindcss-rails from 3.3.1 to 4.0.0.

Release notes

Sourced from tailwindcss-rails's releases.

v4.0.0 / 2025-02-01

Upgrade to Tailwind CSS v4

General changes:

• The dependency on tailwindcss-ruby is set to ~> 4.0.
• The location of (optional) postcss.config.js has moved from the config/ directory to the app root.
• The input file app/assets/tailwind/application.tailwind.css has been renamed to app/assets/tailwind/application.css.
• If Propshaft is being used, app/assets/tailwind will be excluded from its asset handling.
• The Inter font is no longer packaged with the gem.
• Some Tailwind class names in the generated ERB templates are updated for v4.
• The README is updated to contain verbose instructions on upgrading.

Changes to the tailwindcss:install task:

• The tailwindcss:install task no longer installs config/tailwind.config.js, as v4 recommends placing Tailwind configuration in the CSS file.
• The Inter font is no longer configured in the application layout.
• The "tailwind" stylesheet link tag will only be added to the application layout if Propshaft isn't in use and therefore already handling app/assets/build/tailwind.css. Previously it was always injected, resulting in the tag being rendered twice if Propshaft was in use.

New task tailwindcss:upgrade upgrades many apps cleanly:

• Cleans up config/tailwind.config.js and references it from the CSS file as recommended for v4 upgrades.
• Runs the upstream upgrader (note: requires npx to run the one-time upgrade, but highly recommended).
• Removes configuration for the Inter font from the application layout.
• If present, moves config/postcss.config.js to the root directory.
• The "tailwind" stylesheet link tag will be removed if Propshaft is in use and already handling app/assets/build/tailwind.css.
• The input file app/assets/tailwind/application.tailwind.css will be moved to app/assets/tailwind/application.css.

Thanks to @​EricGusmao, @​patriciomacadden, @​excid3, and @​brunoprietog for their feedback, contributions, and advice on v4 support.

Looks like tailwindcss-rails is up-to-date now, so this is no longer needed.
