Add Caishen Readable Codex theme example

[ChannelerH]

What

Adds assets/examples/caishen-readable/, a public-safe Codex-only source theme example for the codedrobe-theme Skill.

This is not a packed .codedrobe-theme artifact and not a store publish. It is a copyable source example that users can adapt, pack, inspect, probe, and verify with CodeDrobe Core.

Included

• Codex-only theme.json with catalog metadata (guofeng, festive, professional)
• codex.css scoped under html.codedrobe-host-codex
• public-safe hero.jpg and low-contrast texture.png assets
• provenance/safety note in ASSET_PROMPTS.md
• references/caishen-readable-example.md
• README / README_zh / Skill routing docs updated to list the new example and remove stale Doll Sister wording

Validation

• npm test
• git diff --check
• npx --yes @codedrobe/core theme pack "$PWD/skills/codedrobe-theme/assets/examples/caishen-readable/theme.json" --output /tmp/caishen-readable-1.0.0-v2.codedrobe-theme
• npx --yes @codedrobe/core theme inspect /tmp/caishen-readable-1.0.0-v2.codedrobe-theme
• Pack/inspect returned targets: ["codex"], imageCount: 3, and warnings: []

Safety

The artwork is adapted from the MIT-licensed public-safe caishen-readable pack in ChannelerH/codex-skin-packs. It contains no private Codex workspace screenshots, task names, chats, sidebars, file paths, project files, application chrome, remote CSS, or scripts.

Thanks for the pointer. I prepared a real CodeDrobe package for this theme instead of only leaving source files in the PR.

Validated package:

• https://codex-theme-gallery.howardhua.chatgpt.site/theme-packs/caishen-readable.codedrobe-theme

Theme page with provenance/install links:

• https://codex-theme-gallery.howardhua.chatgpt.site/themes/caishen-readable?utm_source=codedrobe-skills-pr&utm_medium=github-pr&utm_campaign=codedrobe-package

Validation rerun:

• npx --yes @codedrobe/core theme pack ...
• npx --yes @codedrobe/core theme inspect ... --json
• package id: caishen-readable
• targets: codex
• warnings: []

I also linked the package from the public release notes/site feed/sitemap so it is stable for reviewers and users. I checked codedrobe auth status locally and this environment is signed out, so I am not submitting to the CodeDrobe market under an unauthenticated session from this PR. If you prefer a specific publisher/account flow, I can adapt the package metadata to that submission path.
