// Real desktop-app frames for the teaser's three desktop scenes: the Vite dev server of apps/desktop in fixture mode
// (VITE_FIXTURES=1: example.com-style fixture data, no Tauri, no store accounts), captured headlessly, dark theme,
// with the two dev-build markers hidden (they are not in a release build).
// Writes media/teaser/out/desktop/*.jpg plus boxes.json (cursor and callout targets, as fractions of the frame).
//   portfolio.jpg        Portfolio: every app of every studio, grouped by studio
//   releases.jpg         Prism Puddle's release timeline, both stores rolling out at 20%
//   releases-empty.jpg   the same frame with the rollout bars' fill and "20%" hidden (the video fills the bar)
//   checks.jpg           the Checks tab: the "Rejection risks" card with its findings
//   checks-clean.jpg     the same tab after the fixes: the fixture's scan answer with no findings (the app's own
//                        "No rejection risks found" state; the fixture module is served with an empty findings list)
// render.ts runs it when out/desktop/ is missing; run it by hand after a UI change:  bun media/teaser/desktop.ts
