`build.rs` runs the frontend build in a release profile and skips it in a
debug profile. The split is deliberate: a debug build iterates on the backend
and should not pay for a frontend build, while a release build should produce
one binary with no further steps. `APSIS_WEB_SKIP_FRONTEND=1` forces the skip
one binary with no further steps. `APSIS_BOOK_SKIP_FRONTEND=1` forces the skip
in a release build. A frontend failure is reported as a warning and the last
successful output is embedded, so a release build without network access
still produces a binary.
