// ⛔ static/ must reach the page from INSIDE A BUNDLE.
//
// The router filled /static/ by reading this directory at boot. favela-surface-android runs the
// surface from a bare-pack bundle, which packs only what the module graph imports — so on the phone the
// directory read failed, the catch made it an empty list, and every /static/*.js was a 404. composer.js
// never ran, photos went up with no level pyramid, and bsky got the post without its image.
//
// So the files are IMPORTED (as text), and this checks both halves: nothing reads the directory at
// runtime, and the imported set is exactly what is in static/ — the drift the directory read existed to
// prevent (a file added here and never named is a page that silently does nothing).
