Community: contribute one original StyleSeed skin with rendered evidence

[bitjaru]

Why

Skins are the smallest visual extension surface in StyleSeed: one metadata file and one semantic-token stylesheet. An original community skin is a useful first visual contribution and creates a result the contributor can share.

Scope

Create one original, generically named skin at:

skins/<your-skin>/skin.json
skins/<your-skin>/theme.css

Start from skins/arc/ only as a file-shape reference. Choose a distinct but reusable visual posture—for example archival, botanical, high-contrast editorial, or technical monochrome.

Acceptance criteria

• The name is generic and does not use another company's trademark as the skin identity.
• No logos, copied product layouts, proprietary assets, or protected brand material.
• Required semantic surface, text, action, status, focus, radius, and shadow tokens are present for light and dark modes.
• Contrast remains readable and status colors keep stable meanings.
• npm run build --prefix demo-pricing and git diff --check pass.
• Attach a current screenshot from the generated demo showing the new skin.
• Note any intentional limitation in the PR.

Boundary

A skin changes token material. If the proposal changes component selection, containment, or geometry, stop and open a brand-recipe proposal instead of expanding this PR.

Visual designers and first-time code contributors are welcome to claim this issue.
