COSS for Svelte

Use this skill for the unofficial Svelte 5 port at https://github.com/mielsense/coss-sv. The original COSS project is https://github.com/cosscom/coss.

Workflow

1. Find the exact component page in llms.txt, then read its Markdown page before choosing imports, props, or compound parts.
2. Install the registry item shown on that page. Do not derive an item name from a similar component.
3. Start from the closest documented particle or example and preserve its structure, states, spacing, and interaction contract.
4. Compose compound modules with Svelte namespace syntax such as Card.Header and Dialog.Trigger. Do not translate React-style names such as CardHeader into consumer examples.
5. Verify keyboard behavior, focus, reduced motion, responsive layout, and both color themes.
