// LIF-430: `WebAssets` in src/server.rs embeds web/dist/ via rust-embed, but
// without a build script cargo has no idea the crate depends on those files.
// Rebuild the frontend, run `cargo build --release`, and cargo could declare
// the crate fresh and ship the *previous* bundle embedded in the binary —
// silently. That happened mid-incident during LIF-428 and sent the diagnosis
// down a false path (web/dist held index-DYCyqY48.js while the binary kept
// serving index-C49UV6aq.js).
//
// `rerun-if-changed` on a directory watches it recursively, so any change to
// the built bundle invalidates the crate and forces a re-embed.
