// production serves — an embedded working store has a chunk journal and won't
// open; push it to a file remote first: `dolt push file:///path/bare main`).
// Optionally set BEADS_REAL_ISSUE=<id> to dump one issue's epic rollup and
// merged history. Kept because browse reaches into version-fragile dolt
// internals, so a module bump should be re-verified against real data here.
