Styles arrive through the bundle, and the first components own theirs

[laidrivm]

Step 1 of file-size-cap: styles arrive through the bundle, and the hero tile, the re-pick marker and the dialogs own theirs. app.css goes from 943 lines to 690.

Closes no acceptance criterion. All five land in step 8, which is only possible because the seven steps before it bring the tree under the cap.

Based on chore/dev-serves-the-bundle, which has to merge first — without it the page renders nothing in development.

#85, the scan that checks a component reads only names its module defines, merged into this branch rather than shipping behind it, so its 300 lines are here too.

oversize: step 1 moves app.css a rule at a time, and a moved rule counts twice — the migration alone is ~500 budgeted lines, which is why the change splits it across three steps. #85 merged in on top of that. What a reviewer reads is one CSS migration plus one self-contained test file.

Decisions the task list did not carry:

• The picker reaches into the hero tile twice: the ring on the tile Enter would take, and the fade on a hero already drafted. A scoped class name cannot cross a module boundary, so the tile reads var(--tile-ring, …) and var(--tile-fade, 1) and the picker sets them on its own classes. The alternative, a class prop on HeroTile, puts two single-class selectors on one declaration and lets emission order decide it.
• The confirm dialog is app.tsx's, so its rules go to src/app/app.module.css rather than the picker's stylesheet; step 3 grows that file with the rest of the shell. The bare <dialog> panel both dialogs share has no class to scope and goes to base.css.
• src/css.d.ts declares *.module.css before *.css, and the order is load-bearing: reversed, every read off a module fails to compile.
• The picker's rules inside @media (max-width: 720px) moved with it. Left behind they would have matched nothing, silently.

That nothing was lost in the move was checked by comparing the multiset of declarations and of selectors before and after: 494 declarations against 495, differing only by the four the custom properties account for, and three selectors, being the two that became custom properties and one .picker-hints rule that was duplicated.

To check by hand: the e2e suite locates by role and text, so it cannot see a rule that stopped applying. Worth an eye on the picker on a narrow viewport, on the tile of a hero already drafted, and on the reset dialog's destructive button.

📝 Walkthrough

Walkthrough

The change adds a lexical source scanner, migrates application styles to CSS modules, bundles the global stylesheet, and adds tests for scanner behavior, module class consistency, class composition, and build output.

Changes

CSS module migration and validation

Layer / File(s)	Summary
Lexical source scanner scripts/scan.ts, scripts/scan.test.ts, CLAUDE.md, PLAN.md	Adds blank, which preserves offsets while removing comments, strings, templates, and applicable regular expressions. Tests cover TypeScript and CSS syntax.
CSS module contracts and styles src/css.d.ts, src/app/cx.*, src/app/app.module.css, src/app/board/hero-tile.module.css, src/app/picker/picker.module.css, src/app/styles/base.css	Adds CSS import declarations, the cx helper, dialog styles, picker styles, hero-tile styles, and inherited tile custom properties.
Component CSS module wiring src/app/app.tsx, src/app/board/*, src/app/picker/*, src/app/main.tsx, src/app/styles/app.css	Replaces global component class names with CSS module mappings, imports the global stylesheet through the bundle, and removes migrated global styles.
Build and consistency validation build.test.ts, dist-routes.ts, src/app/module-classes.test.ts	Checks emitted stylesheet links, rejects symlink paths outside dist/, documents route containment, and validates CSS-module references against defined selectors.
Implementation plan updates openspec/changes/file-size-cap/*, PLAN.md	Documents the dist/ serving model, CSS migration scope, scanner status, and completed implementation tasks.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🟡 Moderate · up to e468f

The PR moves styles into component-owned files and adds validation, but the current head can still allow missing CSS-module references to pass undetected and leaves the picker scroll region short of the repository’s accessibility requirement. These issues can affect CI protection and user interaction, so they should be fixed or explicitly accepted before merging.

Inline comments:
In `@build.test.ts`:
- Line 55: Update the assertion near sheets[0] to verify an HTML link element
with rel="stylesheet" whose href references the emitted stylesheet, rather than
merely checking that the href text appears anywhere in the document.

In `@openspec/changes/file-size-cap/design.md`:
- Around line 105-109: Update listed() in static-routes.ts to resolve the
candidate path and enforce canonical containment within dist/ before allowing
access, rejecting symlinks targeting files outside that directory. Add coverage
for a listed symlink pointing to an external file, exercising the guard without
starting a server.
- Around line 97-109: Extend the development-server tests to modify a file under
src/ and verify a subsequent request serves the rebuilt, updated dist/ content.
In dist-routes.ts, canonicalize the requested asset target and reject it when it
falls outside the canonical dist/ directory; add coverage for a top-level
symlink escaping dist/.

In `@openspec/changes/file-size-cap/proposal.md`:
- Around line 95-100: Update the scope statement in the proposal so
src/app/module-classes.test.ts is included in Step 1 work and removed from the
sibling pull-request list; retain only scripts/dev.ts and dist-routes.ts as
separate work, consistent with the Step 1 objective.

In `@openspec/changes/file-size-cap/tasks.md`:
- Around line 44-58: Update task 1.6’s CSS-preservation criterion to account for
shared bare dialog rules moved into base.css, not only the picker and app CSS
modules. State that app.css reductions must match the combined additions across
every required destination, including base.css, while still ensuring no rules
are left behind or duplicated.
- Around line 18-24: Update the delivery record in tasks.md to state that the
component CSS-module class-name scanner and its coverage are delivered in this
change, rather than a separate pull request. Keep the separately delivered Bun
development-server/dist decision unchanged.

In `@scripts/scan.ts`:
- Around line 158-183: Update scripts/scan.ts in the regex and quote scanning
logic to recognize JSX when blanking TSX, preventing tag slashes and apostrophes
in JSX text from being treated as regex or string literals; preserve class reads
after self-closing tags, same-line closing tags, and JSX text apostrophes. Add
corresponding regression cases in scripts/scan.test.ts covering those three
scenarios.

Apply the same fix in `@scripts/scan.test.ts` around lines 10 - 32: The required
regression fixtures are covered by the consolidated scanner and test request.

In `@src/app/module-classes.test.ts`:
- Around line 85-101: Update the CSS-module import scanner around the binding
regex and access expression to recognize valid identifiers containing $,
including imports such as $styles; escape the captured binding before
interpolating it into the generated RegExp, and include $ in the left-side
identifier boundary so matching remains precise. Add a fixture covering a
$-prefixed CSS-module binding and its component-property read.

In `@src/app/picker/picker.module.css`:
- Around line 54-61: Make the pickerGrid scroll region focusable by updating the
corresponding picker component markup to give the grid a suitable focus target,
preserving its existing scrolling behavior and styling.

Bun.Glob scanSync symlink handling and Bun.file URL symlink traversal containment

💡 Result:

Bun provides explicit controls for handling symbolic links in its filesystem operations and runtime, though developers must remain aware of the distinction between filesystem-level traversal and application-level path containment. Bun.Glob Symlink Handling The Bun.Glob class, which provides recursive file scanning, includes options to control symlink traversal [1][2]: - followSymlinks (boolean): When set to true, the scanner will traverse into symbolic link directories [3][2]. It defaults to false [1]. - throwErrorOnBrokenSymlink (boolean): When set to true, the scanner will throw an error if it encounters a broken symbolic link [1][2]. These options are supported in both the synchronous (scanSync) and asynchronous (scan) methods [1]. Bun.file and Path Containment Bun.file returns a reference to a file (a BunFile object) [4]. By default, reading from a BunFile follows symlinks, as this is standard behavior for filesystem operations [5]. Crucially, Bun.file does not natively provide "path containment" or "jail" mechanisms that prevent symlink traversal to locations outside a target directory [5]. If a developer uses Bun.file to access user-supplied paths, they are responsible for ensuring those paths are safe [5]. To implement containment, developers should: - Resolve the canonical path using Bun.realpath before checking if it falls within the expected directory [5]. - Avoid relying solely on string-based path comparisons (like checking if a path starts with a specific prefix), as these are vulnerable to symlink-based path traversal [5]. Security Note While Bun's runtime and internal utilities have implemented robust fixes to prevent symlink-based path traversal in specific contexts—such as archive extraction [6], patch application [7], and module resolution [8][9]—these protections are localized to those features. They do not automatically apply to user-level code using Bun.file or other general-purpose I/O APIs [5]. Developers must proactively validate paths when building features that accept user-controlled filenames or directory paths [5].

Bun.Glob scanSync top-level symlink followSymlinks false does it return symlink files Bun.file follows symlinks

💡 Result:

Regarding your questions on Bun's handling of symbolic links: 1. Bun.Glob scanSync with followSymlinks: false When using Bun.Glob.scanSync (or scan) with followSymlinks set to false (which is the default), the globber does not traverse into symbolic link directories [1][2]. Regarding whether it returns the symbolic link files themselves, the globber's primary purpose is to match and return file paths based on your pattern [1][3]. If a symbolic link file exists at a location that matches your glob pattern, it will be included in the results, as the restriction only prevents the utility from entering (traversing) directories that are symbolic links [1][4]. 2. Does Bun.file follow symlinks? Yes, Bun.file follows symbolic links [5]. When you pass a path to Bun.file, it treats the path as a reference to the file system location [6]. If that path is a symbolic link, Bun will attempt to access the target file that the link points to [5]. If the target does not exist, an error (such as ENOENT) will be thrown when you attempt to read from the file or check its status, revealing that the operation is attempting to resolve the symlink target [5].

Bun.Glob scanSync symlink behaviour and Bun.file URL symlink resolution

💡 Result:

In Bun, symlink behavior for Glob scanning and file operations is handled as follows: ### Bun.Glob scanSync Symlink Behavior The Bun.Glob.scanSync method provides explicit control over symlink traversal through the GlobScanOptions interface [1][2]. * followSymlinks (boolean, default: false): When set to true, scanSync will traverse into directories that are symbolic links [1][2]. If set to false, it ignores the contents of symlinked directories [3]. * throwErrorOnBrokenSymlink (boolean, default: false): When set to true, the method will throw an error if it encounters a broken symbolic link [4][2]. By default, it does not throw, allowing the scan to continue past invalid links [1]. These options are part of the ScanOptions object passed as the second argument to scanSync [1]. ### Bun.file URL Symlink Resolution Bun's Bun.file() function accepts both string paths and URL objects (specifically file:// URLs) [5]. * Handling of URLs: When passed a URL object, Bun treats it as a file reference [5]. If the path refers to a symbolic link, Bun.file() creates a reference to that link [6]. * Symlink Resolution at I/O: Bun.file() itself acts as a lazy reference; it does not immediately resolve the symlink upon construction [6]. When you perform I/O (e.g., calling .text() or .stream()), Bun attempts to open the file. If the path points to a symbolic link, the underlying operating system's open operation resolves the symlink to its target [6]. * Error Reporting: If I/O fails (e.g., a broken symlink resulting in ENOENT), Bun provides diagnostic information that includes both the symlink path and, in many cases, the target path it failed to reach, aiding in debugging [6]. For general module resolution, Bun supports --preserve-symlinks and --preserve-symlinks-main flags, which determine whether Bun keeps the symlink path or resolves to the real path when loading modules or entry points [7][8]. These flags apply to the runtime and the bundler [7][9].

Handle TSX syntax in the scanner and pin it with fixtures. blank(source, "ts") runs on .tsx files, but the current lexical scan treats />, </...> and apostrophes in JSX text as regex or string syntax. That can blank code after those tokens and hide CSS-module class reads. Add TSX-aware handling, or equivalent guards, and cover these cases in scripts/scan.test.ts: a class read after a self-closing tag, after a same-line closing tag, and after an apostrophe in JSX text.

Make the picker scroll region focusable.

.pickerGrid scrolls vertically, but it has no ::scroll-button controls and src/app/picker/picker.tsx does not make the grid itself focusable. Make the grid focusable or provide scroll controls.

As per coding guidelines, “scrollable regions get ::scroll-button or are focusable.”

Do not require HTML attribute order.

Line 59 requires rel before href. A valid <link> can place these attributes in either order, so this test can fail without a broken stylesheet link. Match both attributes with order-independent lookaheads. (html.spec.whatwg.org)

Based on learnings, docs/testing.md says, “Tests must assert observable behaviour rather than mirror implementation details.” As per path instructions, this rule applies to **/*.{ts,tsx}.

Proposed fix

-			new RegExp(`<link[^>]+rel="stylesheet"[^>]+href="\\./${sheets[0]}"`),
+			new RegExp(
+				`<link\\b(?=[^>]*\\brel="stylesheet")(?=[^>]*\\bhref="\\./${sheets[0]}")[^>]*>`,
+			),

List every CSS destination in task 1.6.

Line 58 names app.module.css and base.css, but tasks 1.3 and 1.4 also move rules into hero-tile.module.css and picker.module.css. A comparison limited to the named destinations can omit moved declarations. Name every destination, or refer to the complete destination set.
