Walkthrough

Migrate most SCSS from legacy @import to Sass modules (@use/@forward) and add a theme entrypoint; upgrade tooling (Yarn→v4, Angular→v20, Storybook→v9, ESLint flat-config); replace gulp-dart-sass with dart-sass API in build scripts; remove ComponentFactoryResolver usages from portal/host code; refactor TableComponent template/providers; enable Corepack in CI and adjust related scripts.

Changes

Cohort / File(s)	Summary
Storybook config & stories .storybook/global.scss, .../.storybook/main.ts, .../.storybook/manager.ts, .../.storybook/preview.ts, stories/*/*.mdx	Switch Storybook SCSS @import → @use; remove legacy addons from .storybook/main.ts; change some Storybook import paths (@storybook/manager-api → storybook/manager-api); update MDX imports to @storybook/addon-docs/blocks.
Tooling & CI .stylelintrc, .yarnrc.yml, eslint.config.mjs, package.json, .github/workflows/*.yml	Add Yarn v4 config and npm mirror, enable Corepack steps in CI workflows, add Stylelint SCSS override, migrate ESLint to flat-config (FlatCompat), bump Angular/TS/Storybook and add sass/sass-loader/tslib; update lint scripts and packageManager.
Build & resource scripts scripts/build.js, scripts/copy-resources.js, scripts/publish-version.js, scripts/run-lint.js	Remove gulp-dart-sass; use sass (Dart Sass) compileString API, copy SCSS partials and CDK CSS via fs, ensure destination dirs and error handling; change dist-tags fetch to npm view; add scripts/run-lint.js to run linters/tsc in parallel.
Theme system & entrypoint src/theme/*, src/theme/index.scss, src/theme/motion/*, src/theme/_var.scss, src/theme/_mixin.scss	Add src/theme/index.scss; convert theme modules to @use/@forward; namespace modules (e.g., var, mixin, base-var, motion); change mixin defaults to var-based durations and migrate helpers to var.use-*/CSS-var-backed forms.
Bulk SCSS migration src/**/*.scss (many files; e.g., src/**/.../*.scss, src/accordion/**, src/button/**, src/date-picker/**, etc.)	Large mechanical refactor: replace @import with @use/@forward, add module aliases (commonly var, mixin, others), qualify mixins/functions (mixin.*, var.use-*), add @use 'sass:map' and convert map-get→map.get where applicable; minor local adjustments.
Portal / DI removals src/anchor/anchor.directive.ts, src/select/helper-directives.ts, src/message/base-message.ts, src/message/message.service.ts, src/notification/notification.service.ts	Remove ComponentFactoryResolver from constructors/usages; stop passing it into DomPortalOutlet and super calls; adjust constructor signatures.
Table component refactor src/table/table.component.ts	Replace CDK-internal template/providers with an inline template that supports native HTML table and non-native paths; remove _COALESCED_STYLE_SCHEDULER provider and reduce CDK internals.
Small Angular edits & lint cleanup src/date-picker/calendar/header/component.ts, src/dialog/dialog-content/dialog-content.component.ts, src/select/validators.ts, src/notification/notification.config.ts	Use inject() in a component, remove unused imports/pipes, and delete several inline ESLint suppression comments; no algorithmic changes.
Trivial removals src/message/message-wrapper.component.scss, src/notification/notification-wrapper.component.scss, src/tabs/tab-group.component.scss	Remove unused theme import lines or blank lines; no behavioral/style changes beyond import removal.

Poem

I thump my paws on fresh new ground,
Old imports swapped for modules sound 🧶
Portals slimmer, tables reframe,
Themes gathered under one name.
Yarn and stories hop — hooray, spring! 🐇✨
