Completes `var(--…)` from the custom properties declared in the workspace, with the value shown beside each.

Runs the workspace’s ESLint in the editor — problems inline, fix-on-save — so the pre-commit hook rarely has anything left to say.

Previews Iconify icons inline where their names appear — `i-tabler-rss`, `logos:figma` — and completes them from the installed collections.

A slide outline beside the deck’s Markdown, a preview pane, and slide-level navigation, for the decks in the slides repository.

Class-name completion, hover previews of the generated CSS, and lint for conflicting utilities, reading the project’s own Tailwind config and theme.

Runs and debugs Vitest from the Test Explorer — one test, one file, or the project — with inline results and watch mode, against this repository’s `unit` and `nuxt` projects.

The Vue language server — template type-checking, completion for props and events, go-to-definition across `<script setup>` — the same engine `vue-tsc` runs in the typecheck gate.
