Bumps tailwindcss from 3.4.18 to 4.3.0.

Release notes

Sourced from tailwindcss'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)

v4.2.4

Fixed

  • Ensure imports in @import and @plugin still resolve correctly when using Vite aliases in @tailwindcss/vite (#19947)

v4.2.3

Fixed

  • Canonicalization: improve canonicalizations for tracking-* utilities by preferring non-negative utilities (e.g. -tracking-tightertracking-wider) (#19827)
  • Fix crash due to invalid characters in candidate (exceeding valid unicode code point range) (#19829)
  • Ensure query params in imports are considered unique resources when using @tailwindcss/webpack (#19723)
  • Canonicalization: collapse arbitrary values into shorthand utilities (e.g. px-[1.2rem] py-[1.2rem]p-[1.2rem]) (#19837)
  • Canonicalization: collapse border-{t,b}-* into border-y-*, border-{l,r}-* into border-x-*, and border-{t,r,b,l}-* into border-* (#19842)
  • Canonicalization: collapse scroll-m{t,b}-* into scroll-my-*, scroll-m{l,r}-* into scroll-mx-*, and scroll-m{t,r,b,l}-* into scroll-m-* (#19842)
  • Canonicalization: collapse scroll-p{t,b}-* into scroll-py-*, scroll-p{l,r}-* into scroll-px-*, and scroll-p{t,r,b,l}-* into scroll-p-* (#19842)
  • Canonicalization: collapse overflow-{x,y}-* into overflow-* (#19842)
  • Canonicalization: collapse overscroll-{x,y}-* into overscroll-* (#19842)
  • Read from --placeholder-color instead of --background-color for placeholder-* utilities (#19843)
  • Upgrade: ensure files are not emptied out when killing the upgrade process while it's running (#19846)
  • Upgrade: use config.content when migrating from Tailwind CSS v3 to Tailwind CSS v4 (#19846)
  • Upgrade: never migrate files that are ignored by git (#19846)

Drift Compliance: All test vectors passed GI threshold validation

kaizencycle added a commit that referenced this pull request Jun 11, 2026
… taken, 1 corrected, 3 held) (#315)

## EPICON Intent Block

- **Intent:** Consolidate the five open Dependabot PRs (#310#314) into
one reviewable change with per-dependency judgment, per operator request
("check if they are safe to merge, if not, unify them to one big PR for
safety").
- **Scope:** `package-lock.json`, three workspace `package.json` files,
`.github/dependabot.yml` ignore rules. No workflow, canon, or attested
content touched.
- **Actor:** Claude Code under operator identity, C-339.
- **Consequence class:** Dependency hygiene — net reduction of
unreviewed major-version churn.

## Safety verdict per PR

| PR | Bump | Verdict | Disposition |
|---|---|---|---|
| #310 | `@vercel/node` 5.8.16→5.8.17 | ✅ Safe (patch, in-range of
`^5.5.15`) | **Taken** — lockfile updated |
| #312 | `@types/node` 18→**25** | ⚠️ Wrong target — repo runtime is
**Node 20** | **Taken as 18→20**: `^18.0.0`→`^20.0.0` in
`packages/atlas-sentinel`, `sentinels/atlas`, `sentinels/uriel`;
lockfile dedupes to one 20.x. Ignore rule for `@types/node >=21` |
| #311 | `hardhat-chai-matchers` 2→3 | ❌ Incompatible — requires hardhat
3; `gic-registry-contracts` pins `hardhat 2.22.5` | **Held** via ignore
rule; bump belongs in a hardhat-3 migration |
| #313 | `http-proxy-middleware` 2→4 | ❌ Two majors; v3 rewrote the
`createProxyMiddleware` API that `apps/api-gateway` uses | **Held** via
ignore rule |
| #314 | `tailwindcss` 3→4 | ❌ v4 is a CSS-first config rewrite; **8
apps** pin `^3.4.x` with `tailwind.config.js` | **Held** via ignore
rule; migrate deliberately, not via dep bump |

The ignore rules follow the repo's own precedent (#308, ESLint held at
8.x), each with a comment stating the unblock condition so they're
revisitable, not permanent.

## Lockfile diff verification

Verified the lock diff contains **only**: `@vercel/node` 5.8.16→5.8.17,
removal of nested `@types/node` 18.19.130 copies (dedupe to root
20.19.43), in-range nested 22.19.1→22.19.21 refreshes, and the
`undici-types` transitive. No major versions moved.

## After merge

Dependabot auto-closes #310#314 on its next run: #310/#312 because the
dependencies moved, #311/#313/#314 because of the ignore rules. No
manual closing needed.

**Residual risk:** the three packages whose types moved 18→20 are
type-checked in CI, not locally (worktree had no `node_modules`) — if
CI's type-check flags anything, I'll fix on this branch.

Looks like tailwindcss is no longer being updated by Dependabot, so this is no longer needed.
