// Build demo state for playground v3.
//
// Reads all fixtures from playground/test-fixtures/*.md and inlines them as a
// <script type="application/json" id="demo-state-v1"> block in the playground
// HTML. The "Last inn demo-data" button on the onboarding surface reads this
// block and bootstraps a complete demo: filled organization, one demo project,
// all 17 reports pre-imported as raw_markdown.
//
// Idempotent: detects existing block by id and replaces it; otherwise injects
// after </main>. Run from plugin root (or anywhere — uses script-relative paths).
//
// Usage: node scripts/build-demo-state.mjs
