Ivory 0.2.4

Fixed

• Restore the Ivory body class automatically if DSH rewrites document.body.className during appearance or session transitions, preventing the light theme from falling back to the native white page background.

Validation

• npm test — release-check 14/14, publint, pack verification
• npm run qa:adversarial — 27/27
• npm run qa:activity — 13/13
• npm run qa:r2 — 69/69

This release does not bundle Anthropic/Claude font binaries; the local font overlay remains private and excluded from the npm package.
