The operator hand-pushed .env and .env.ove tracked while this task ran,
both with DATABASE_URL="file:./db/custom.db" — the relative form that
Prisma resolves against prisma/schema.prisma's directory, i.e. to
<repo>/prisma/db/custom.db, breaking the CLI (db push would silently
create a fresh empty database there) and the runtime (cannot open);
verified empirically. The merge keeps .env tracked per the operator's
explicit action (gitignore: !.env) and corrects DATABASE_URL in both
files to the portable file:../db/custom.db. The committed .env is held
byte-identical to .env.ove so dev.sh's self-heal copy never leaves a
dirty tree.
