-Built with TypeScript, Preact, and unified/remark/rehype for markdown processing.
-
-| Stack         | Technology                                |
-| ------------- | ----------------------------------------- |
-| Language      | TypeScript 5.x (strict mode)              |
-| Runtime       | Node.js >=22 (v22.16.0 pinned)            |
-| Package Mgr   | npm >=10.9.2                              |
-| Module System | ES Modules (`"type": "module"`)           |
-| UI Framework  | Preact 10.x (JSX with `react-jsx` pragma) |
-| Build Tool    | esbuild                                   |
-| Styling       | SCSS via esbuild-sass-plugin              |
-
-## Environment
-
-This is a Nix project. Use the provided `flake.nix` to enter a dev shell with Node.js 22 and npm:
-
-```bash
-nix develop
-```
-
-All `npm` commands below must be run inside the dev shell.
-
-## Build, Lint, and Test Commands
-
-```bash
-# Type check and format check (CI validation)
-npm run check
-
-# Auto-format code with Prettier
-npm run format
-
-# Run all tests
-npm run test
-
-# Run a single test file
-npx tsx --test quartz/util/path.test.ts
-
-# Run tests matching a pattern (use --test-name-pattern)
-npx tsx --test --test-name-pattern="typeguards" quartz/util/path.test.ts
-
-# Build the static site
-npx quartz build
-
-# Build and serve with hot reload
-npx quartz build --serve
-
-# Profile build performance
-npm run profile
-```
-
-### Test Files Location
-
-Tests use Node.js native test runner via `tsx`. Test files follow the `*.test.ts` pattern:
-
-- `quartz/util/path.test.ts`
-- `quartz/util/fileTrie.test.ts`
-- `quartz/components/scripts/search.test.ts`
-
-## Code Style Guidelines
-
-### Prettier Configuration (`.prettierrc`)
-
-```json
-{
-  "printWidth": 100,
-  "tabWidth": 2,
-  "semi": false,
-  "trailingComma": "all",
-  "quoteProps": "as-needed"
-}
-```
-
-**No ESLint** - only Prettier for formatting. Run `npm run format` before committing.
-
-### TypeScript Configuration
-
-- **Strict mode enabled** (`strict: true`)
-- `noUnusedLocals: true` - no unused variables
-- `noUnusedParameters: true` - no unused function parameters
-- JSX configured for Preact (`jsxImportSource: "preact"`)
-
-### Import Conventions
-
-```typescript
-// 1. External packages first
-import { PluggableList } from "unified"
-import { visit } from "unist-util-visit"
-
-// 2. Internal utilities/types (relative paths)
-import { QuartzTransformerPlugin } from "../types"
-import { FilePath, slugifyFilePath } from "../../util/path"
-import { i18n } from "../../i18n"
-```
-
-### Naming Conventions
-
-| Element          | Convention   | Example                             |
-| ---------------- | ------------ | ----------------------------------- |
-| Files (utils)    | camelCase    | `path.ts`, `fileTrie.ts`            |
-| Files (comps)    | PascalCase   | `TableOfContents.tsx`, `Search.tsx` |
-| Types/Interfaces | PascalCase   | `QuartzComponent`, `FullSlug`       |
-| Type Guards      | `is*` prefix | `isFilePath()`, `isFullSlug()`      |
-| Constants        | UPPER_CASE   | `QUARTZ`, `UPSTREAM_NAME`           |
-| Options types    | `Options`    | `interface Options { ... }`         |
-
-### Branded Types Pattern
-
-This codebase uses branded types for type-safe path handling:
-
-```typescript
-type SlugLike<T> = string & { __brand: T }
-export type FilePath = SlugLike<"filepath">
-export type FullSlug = SlugLike<"full">
-export type SimpleSlug = SlugLike<"simple">
-
-// Always validate with type guards before using
-export function isFilePath(s: string): s is FilePath { ... }
-```
-
-### Component Pattern (Preact)
-
-Components use a factory function pattern with attached static properties:
-
-```typescript
-export default ((userOpts?: Partial<Options>) => {
-  const opts: Options = { ...defaultOptions, ...userOpts }
-
-  const ComponentName: QuartzComponent = ({ cfg, displayClass }: QuartzComponentProps) => {
-    return <div class={classNames(displayClass, "component-name")}>...</div>
-  }
-
-  ComponentName.css = style           // SCSS styles
-  ComponentName.afterDOMLoaded = script  // Client-side JS
-  return ComponentName
-}) satisfies QuartzComponentConstructor
-```
-
-### Plugin Pattern
-
-Three plugin types: transformers, filters, and emitters.
-
-```typescript
-export const PluginName: QuartzTransformerPlugin<Partial<Options>> = (userOpts) => {
-  const opts = { ...defaultOptions, ...userOpts }
-  return {
-    name: "PluginName",
-    markdownPlugins(ctx) { return [...] },
-    htmlPlugins(ctx) { return [...] },
-    externalResources(ctx) { return { js: [], css: [] } },
-  }
-}
-```
-
-### Testing Pattern
-
-Use Node.js native test runner with `assert`:
-
-```typescript
-import test, { describe, beforeEach } from "node:test"
-import assert from "node:assert"
-
-describe("FeatureName", () => {
-  test("should do something", () => {
-    assert.strictEqual(actual, expected)
-    assert.deepStrictEqual(actualObj, expectedObj)
-    assert(condition) // truthy assertion
-    assert(!condition) // falsy assertion
-  })
-})
-```
-
-### Error Handling
-
-- Use `try/catch` for critical operations (file I/O, parsing)
-- Custom `trace` utility for error reporting with stack traces
-- `process.exit(1)` for fatal errors
-- `console.warn()` for non-fatal issues
-
-### Async Patterns
-
-- Prefer `async/await` over raw promises
-- Use async generators (`async *emit()`) for streaming file output
-- Use `async-mutex` for concurrent build protection

-## Branch Workflow
-
-This is a fork of [jackyzha0/quartz](https://github.com/jackyzha0/quartz) with org-roam customizations.
-
-| Branch      | Purpose                                          |
-| ----------- | ------------------------------------------------ |
-| `main`      | Clean mirror of upstream quartz — no custom code |
-| `org-roam`  | Default branch — all customizations live here    |
-| `feature/*` | Short-lived branches off `org-roam`              |
-
-### Pulling Upstream Updates
-
-```bash
-git checkout main
-git fetch upstream
-git merge upstream/main
-git checkout org-roam
-git merge main
-# Resolve conflicts if any, then commit
-```
-
-### Working on Features
-
-```bash
-git checkout org-roam
-git checkout -b feature/my-feature
-# ... work ...
-git checkout org-roam
-git merge feature/my-feature
-git branch -d feature/my-feature
-```
-
-**Merge direction:** `upstream → main → org-roam → feature/*`
-
-## Org-Roam Workflow
-
-Notes live in a **separate directory** outside this repo. The export script
-converts them to Markdown via ox-hugo, then Quartz builds the site.
-
-### Tooling
-
-The dev shell (`nix develop`) provides:
-
-- `nodejs_22` — Quartz build
-- `elixir` — runs the export script
-- `emacs` + `ox-hugo` — performs the org → markdown conversion
-
-### Export and build
-
-```bash
-# Export only (wipes content/, exports all .org files)
-NOTES_DIR=/path/to/notes npm run export
-
-# Export then build the site
-NOTES_DIR=/path/to/notes npm run build:notes
-
-# Positional arg also works
-elixir scripts/export.exs /path/to/notes
-```
-
-The export script (`scripts/export.exs`) runs Emacs in batch mode, calling
-`org-hugo-export-to-md` per file (per-file mode, not per-subtree). It uses
-YAML frontmatter (ox-hugo default). `content/` is wiped before each export.
-
-## Important Notes
-
-- **Client-side scripts**: Use `.inline.ts` suffix, bundled via esbuild
-- **Isomorphic code**: `quartz/util/path.ts` must not use Node.js APIs
-- **Incremental builds**: Plugins can implement `partialEmit` for efficiency
-- **Markdown flavors**: Supports Obsidian (`ofm.ts`) and Roam (`roam.ts`) syntax

-## Quick Start
-
-### Prerequisites
-
-This project uses Nix. Enter the development shell, which provides Node.js 22, Elixir, and Emacs with ox-hugo:
-
-```bash
-nix develop
-```
-
-All commands below must be run inside this shell.
-
-```bash
-npm install
-```
-
-### Building from org-roam notes
-
-Your org-roam notes live in a separate directory. Point `NOTES_DIR` at it:
-
-```bash
-# Export notes to content/ and build the site
-NOTES_DIR=/path/to/notes npm run build:notes
-
-# Export, build, and serve with hot reload
-NOTES_DIR=/path/to/notes npm run serve:notes
-
-# Export only (wipes content/ and re-exports all .org files)
-NOTES_DIR=/path/to/notes npm run export
-```
-
-The export script mirrors the subdirectory structure of your notes into `content/`
-and generates a fallback `index.md` if your notes don't include one.
-
-### Building without org-roam notes
-
-If you manage `content/` directly with Markdown files:
-
-```bash
-# Build the site
-npx quartz build
-
-# Build and serve with hot reload
-npx quartz build --serve
-```
-
-The site is generated in `public/`. When serving, visit http://localhost:8080.
-
-### Development
-
-```bash
-npm run check    # type check + format check
-npm run format   # auto-format with Prettier
-npm run test     # run tests
-```
