-- Memory limit: configurable via `sandlot config memory` (default 16G)
+- Memory limit: 4G
 - Mounts: `~/dev` **read-only** at `/host`, `~/.sandlot` read-write at `/sandlot`
 - Host symlinks: creates `~/dev` → `/host` and `~/.sandlot` → `/sandlot` inside the container so host-absolute worktree paths resolve correctly
 - `containerPath()` in `vm.ts` translates host paths to container paths (`~/.sandlot/…` → `/sandlot/…`, `~/dev/…` → `/host/…`)

-```bash
-sandlot config              # show all options and current values
-sandlot config memory       # show current memory setting
-sandlot config memory 32G   # set container memory limit

-Config is stored in `~/.config/sandlot/config.json`.
