Closes BON-9.

The framework-agnostic root entry (boneAttributes, minMax, resolveLength, TRANSPARENT_PIXEL) had one README row and no demo. This PR gives it both halves the issue asked for.

Vanilla demo (apps/vanilla)

A new workspace app with no React: an index.html card shell and a ~40-line main.ts that imports @camp.dev/bones/css and the root entry. src/apply.ts holds the whole vanilla "renderer": applyBone copies the attribute contract onto a live element and clearBone takes it off. A button toggles the card between bones and content. Run it with vp run --filter bones-vanilla dev (or vp run vanilla from the root).

Verified in headless Chromium: the loading state paints an avatar bone and three shimmer bars with minMax-varied widths, and toggling swaps in the real content.

Docs page (/api/bone-attributes)

apps/docs/content/docs/api/bone-attributes.mdx documents the root entry around the same card example, in the format of the existing API pages: parameters, per-type return values, minMax, resolveLength (including the deterministic width formula and why server and client renders agree), isMinMax, TRANSPARENT_PIXEL, and the type signature. Added to the API nav after bones-boundary.

CI

Three new jobs mirror the stream app's: vanilla-check (tsc), vanilla-test (3 jsdom tests for applyBone/clearBone, written first, watched fail), and vanilla-build (vite build).

Not touched: vp check reports formatting issues in three files already failing on main (apps/demo/app/globals.css, apps/demo/components/suspense-demo/suspense-demo.test.tsx, apps/docs/components/logo.tsx).

Summary by CodeRabbit

  • New Features

    • Added a vanilla JavaScript profile-card demo with avatar, text, and loading placeholders.
    • Added a control to toggle between loading and loaded profile content.
    • Added reusable helpers for applying, displaying, and clearing loading states on HTML elements.
  • Documentation

    • Added comprehensive API documentation for bone attributes, sizing helpers, loading states, and usage examples.
  • Tests

    • Added coverage for loading attributes, styles, placeholders, line generation, and cleanup behavior.
  • Chores

    • Added automated type-check, test, and build validation for the vanilla demo.

The framework-agnostic root entry had one README row and no demo. apps/vanilla
is a plain HTML + TypeScript Vite app: applyBone/clearBone copy the
boneAttributes contract onto live elements, and a button toggles the card
between bones and content. The docs get api/bone-attributes.mdx, which
documents boneAttributes, minMax, resolveLength, isMinMax, and
TRANSPARENT_PIXEL around the same card example.

📝 Walkthrough

Walkthrough

Adds a framework-agnostic bone attribute API reference and a vanilla demo. The demo applies and clears loading placeholders, includes DOM helper tests, and adds CI jobs for type checking, testing, and building.

Changes

Vanilla demo integration

Layer / File(s) Summary
Bone attribute API documentation
apps/docs/content/docs/api/bone-attributes.mdx, apps/docs/content/docs/api/meta.json
Documents bone attribute helpers, types, return values, length resolution, and browser usage. Adds the page to the API navigation.
Vanilla loading demo
apps/vanilla/package.json, apps/vanilla/src/css.d.ts, apps/vanilla/src/apply.ts, apps/vanilla/index.html, apps/vanilla/src/main.ts, package.json
Adds the vanilla package and demo page. The application toggles profile loading state and applies or clears bone metadata and styles.
Vanilla tooling and validation
apps/vanilla/tsconfig.json, apps/vanilla/vite.config.ts, apps/vanilla/test/apply.test.ts, .github/workflows/ci.yml
Adds TypeScript and Vite test configuration. Tests bone application and cleanup. CI runs type checks, tests, and builds for the vanilla package.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 6445d

The PR adds CI jobs that retain checkout credentials while running checked-out code, creating a bounded credential-exposure risk, and its vanilla demo cleanup can leave image elements pointing at a transparent placeholder after bones are cleared. Merge should wait for these issues to be fixed or explicitly accepted by the owner.

Official actions/checkout v4 documentation: default value and security behavior of persist-credentials

💡 Result:

In the actions/checkout@v4 action, the persist-credentials input has a default value of true [1][2][3]. Security Behavior and Context: When persist-credentials is set to true (the default), the action configures the authentication token (such as the GITHUB_TOKEN or a provided Personal Access Token) into the local Git configuration of the checked-out repository [1][4]. This allows subsequent steps in the workflow to execute authenticated Git commands (e.g., git push or git pull) without requiring additional configuration [1][4]. The token is automatically removed during the post-job cleanup process [1][4]. Security Considerations: - Exposure Risk: Because the credentials are stored in the local .git/config file, there is a risk that they could be exposed if the workspace (or specifically the .git directory) is inadvertently uploaded, archived, or exposed to other processes or external services during the job [5]. - Opt-out: Users concerned about this risk can set persist-credentials: false to prevent the action from writing the credentials to the local Git configuration [1][4]. - Workflow Security: While this behavior is standard, it is recommended to ensure that subsequent steps in the workflow do not export or expose the contents of the .git directory [5]. Discussions within the community have highlighted this default as a potential area for security hardening, noting that care should always be taken when handling write-enabled Git tokens [6].

Citations:


Disable persisted checkout credentials in the three vanilla CI jobs.

If these jobs do not require authenticated Git operations, set persist-credentials: false on each actions/checkout@v4 step. The pull_request workflow otherwise writes the read-only GITHUB_TOKEN to .git/config, where commands from the checked-out revision can read it.

Skipping here for consistency: all twelve existing checkout steps in this workflow use the default. Worth hardening workflow-wide in a separate change.

@hunterbecton, agreed. Keep this workflow consistent in this pull request. The credential hardening should update all checkout steps together in a separate change.

Would you like me to open a follow-up GitHub issue for the workflow-wide update?

CodeRabbit follow-ups: clearBone now removes the src it set when it is
still the transparent pixel (and leaves a real src alone), in the app and
in the docs example. The docs type signature notes the private brand that
isMinMax checks for.

The bio wraps to two lines but its skeleton drew a single bar. lineBones
fills a wrapper with span[data-bone-line] children, one text bone per
expected line, matching the markup the React lines() helper renders. The
docs example gains the same helper and a paragraph explaining it.
