…uild Core builds the stylesheet that the whole shell uses, but it only scanned its own sources and the shared UI library. Six of the eight remotes never inject a stylesheet of their own - their styles.css is imported from src/index.js, the standalone dev entry that core never loads - so every utility they use that core does not use is simply missing today: cursor-grab, border-l-4, h-[320px], max-w-[525px] and 45 more in team_allocation alone. Scanning the sibling component directories makes core's sheet a superset of what any remote renders, which is the precondition for dropping the remotes' duplicate Tailwind builds.
…sheet Every remote compiled a full Tailwind stylesheet. assessment and presentation imported theirs from the federated entry points, so it landed in the host's <head> after core's and won every equal-specificity duel: core's <Input className='pl-9'> lost padding-left to the remote's copy of .px-3. Ordering the sheets cannot fix that. Tailwind utilities are globally named, so a layer order or an insertion anchor can only pick one winner for every element; making the host win means a remote can no longer override a shared component's base class either. Being right in both directions needs a single sheet, which core now builds. The other six remotes only imported their sheet from src/index.js, the standalone dev entry core never loads, and every standalone page renders nothing but a 'load this from core' notice. So the eight builds bought no workflow, and deleting the entry points makes the invariant structural rather than a rule someone has to remember. Assessment's print rules move to a plain print.css, which carries no Tailwind directives and stays imported from routes/.
pl-9! only existed because a remote's stylesheet could override .pl-9 with its own .px-3. Core now builds the only Tailwind sheet in the document, so the plain utility wins on its own.
Loads the remote, walks back to the courses list through the sidebar, and checks the search field still gets its 36px padding from a plain pl-9. The walk has to stay in the same document: page.goto() would reload and drop whatever the remote injected, so the assertion would pass on a broken build too. A window marker set before the click fails the test if that ever happens. The sidebar's home button gets a test id because it renders through asChild and has no accessible name to target.
Records the rule and the reason in the four places a contributor would look: the Module Federation and shadcn rules, the shared scaffolding readme, and the client guide. The new-phase guide gets the external-repository caveat, since core cannot scan a repository it does not have.

… entry clients/readme.md asked every component for a tailwind.config.js importing the shared preset, and the reusable-components guide asked for a styles.css import next to the tiptap stylesheet. Neither exists any more.

Official actions/checkout documentation persist-credentials default
💡 Result:
In the actions/checkout GitHub Action, the persist-credentials input defaults to true [1][2][3]. When set to true, the action configures the authentication token or SSH key with the local Git configuration, which allows subsequent scripts in the job to run authenticated Git commands [1][4]. The action automatically removes these credentials during post-job cleanup [1][5]. While there have been community discussions and pull requests proposing to change this default value to false to enhance security [6], as of August 23, 2026, the official documentation and the action's configuration files (action.yml) maintain a default value of true [1][2][3]. Users who wish to opt out of this behavior and prevent the credential from being persisted in the local Git configuration should explicitly set persist-credentials: false in their workflow configuration [1][4].

Summary
clients/corenow builds the only Tailwind stylesheet in the document and scans everymicro-frontend for it, and the eight phase components stop compiling Tailwind altogether. This
removes the cascade collision from #2086, where a remote's injected stylesheet overrode core's
utilities, and it also fixes the mirror-image bug where a remote's utilities were never emitted at
all.
Details
Two problems, one root cause.
Remotes overriding core.
assessment_componentandpresentation_componentimported theirstyles.cssfrom their federated entry points, sostyle-loaderappended a second completeTailwind build to
<head>after core's. Both sheets carry the same globally named utilities, so thelater one won every equal-specificity duel: on
<Input className='pl-9'>the remote's.px-3beatcore's
.pl-9, and the course search icon overlapped the placeholder.Remotes with no styles at all. The other six remotes only imported
styles.cssfromsrc/index.js, the standalone dev entry that core never loads, so inside the shell they silentlydepended on core's utility vocabulary. Core did not scan them, so every utility they used that core
did not use was missing: 49 of them in
team_allocation_componentalone, includingcursor-grab,border-l-4,h-[320px],h-[420px]andmax-w-[525px], plus 15 ininterview_componentand 10in
self_team_allocation_component.Ordering the two sheets cannot fix the first problem. A
@layerorder or astyle-loaderinsertionanchor can only pick one winner for every element, so making the host win means a remote can no
longer override a shared component's base class either, and reversing it restores #2086. Being right
in both directions needs a single sheet.
Changes:
clients/core/tailwind.config.jsscans../*_component/{src,routes,sidebar}on top of its ownsources and the shared UI library. Its theme was already a strict superset of the library preset
the remotes used, so nothing had to be merged.
*_componentlosessrc/styles.css,tailwind.config.jsand its CSS import.assessment_component/src/loadStyles.jsis gone; its@media printrules move to a plainsrc/print.cssthat carries no Tailwind directives and stays imported fromroutes/. Thestandalone dev pages render nothing but a "load this from core" notice, so no workflow is lost,
and with the entry points deleted the invariant is structural rather than a rule to remember.
pl-9!inCourseCards.tsxgoes back topl-9, which is what the fix has to prove.scripts/check-remote-styles.shfails CI if a component reintroduces atailwind.config.*or any@tailwind,@config,@source,@applyortailwindcssimport in its CSS. It runs in its ownjob so it does not repeat nine times over the quality matrix. Plain CSS stays allowed.
Module Federation and shadcn rules,
clients/shared/readme.md, and the client guide.One consequence worth knowing: because core scans its siblings, its stylesheet is only complete for
the commit it was built from. CI already guarantees that (every client image is built from the same
clients-basetag), but a deployment that mixes per-service image tags across clients could leaveutilities out. The new-phase guide records the matching caveat for out-of-repo phases, which core
cannot scan at all.
Reason / Link to issue
Closes #2086.
How to Test
cd clients && yarn --cwd core build.grep -c 'cursor-grab{' core/build/main.*.jsis 1, so autility only
team_allocation_componentuses is now in core's sheet.yarn --cwd assessment_component build, then! grep -rl 'px-3{' assessment_component/buildpasses: no remote emits utilities any more../scripts/check-remote-styles.shpasses, and fails once you add@import 'tailwindcss';to any component stylesheet.make db && make server && make clients, log in, open an assessment phase so the remote loads,then use the sidebar home button to go back to the courses list without reloading. The search
field keeps its 36px left padding and the icon no longer sits on the placeholder.
cursor-graband the panelsget their
h-[320px]/h-[420px]heights, none of which rendered before.make test-e2e-shard SHARD=assessmentcovers steps 4 in CI.Screenshots
The visual change is the one #2087 patched with an important modifier: in the card view of
/management/general, the course search placeholder starts clear of the magnifier icon. It nowholds without the modifier, after any remote has been loaded.
