v2.1.3

One repo, one skill. `design-taste-frontend` itself is unchanged; this release cleans up the repo around it ([#153](https://github.com/Leonxlnx/taste-skill/issues/153), [#155](https://github.com/Leonxlnx/taste-skill/pull/155)).

**The other skills moved to repos of their own and kept their install names:**

- The classic styles and earlier versions (`high-end-visual-design`, `minimalist-ui`, `industrial-brutalist-ui`, `gpt-taste`, `stitch-design-taste`, `design-taste-frontend-v1`, `design-taste-frontend-v2-experimental`) are in **[Leonxlnx/taste-skill-classics](https://github.com/Leonxlnx/taste-skill-classics)**.
- The image-generation skills (`imagegen-frontend-web`, `imagegen-frontend-mobile`, `brandkit`, `image-to-code`) are in **[Leonxlnx/imagegen-skills](https://github.com/Leonxlnx/imagegen-skills)**.
- `redesign-existing-projects` is part of `design-taste-frontend`.

Installed a classic skill from this repo before? Install it from its new home under the same name:

```bash
npx skills add https://github.com/Leonxlnx/taste-skill-classics --skill "high-end-visual-design"
```

Claude Code plugin users: `taste-skill@taste-skill` is unchanged. The classics plugin now has its own marketplace: `/plugin marketplace add Leonxlnx/taste-skill-classics`.

Also in this release:

- A cleaner README, with a wordmark instead of the banner and a TasteCode banner that reads well in dark mode.
- Old research notes, `llms.txt`, `skill.sh` and unused images are removed.
- The Codex plugin now loads only `design-taste-frontend`.

Thanks to @code5717 for the nudge in #153.
