Design system export command (/export-design-system)

[PAMulligan]

Goal

v2.0.0 scopes "design system export." Needs a concrete command, an output format, and a defined consumer.

Acceptance criteria

• Slash command /export-design-system defined under .claude/commands/
• Output format documented (Style Dictionary? CSS variables + JSON?)
• Consumer for the export documented (e.g., importable by Flavian theme.json, Nerva theme tokens, etc.)
• Round-trip test: tokens → export → reimport produces identical token lockfile

Milestone

v2.0.0
