 ## VRAM booster
 
 SteamOS 3.9 manages the dGPU's VRAM per cgroup: the game in front is

 by the desktop and other apps, and stutter. The kernel side is the `dmem`

+| Where | What |
+|---|---|
+| `~/.local/state/steamify/` | State (`*.state`), undo journals (`*.journal`), the saved panel layout (`theme-layout/`) |
+| `~/.local/share/steamify/app/` | The app (`steamify-app.sh` downloads it here) |

+| `~/.config/systemd/user/` | `steamify-update-check.*`, `steam-desktop-autostart.service` |
+
+System-wide: `/usr/local/lib/steamify/` (kernel headers script),
+`/usr/src/steamify-*` (DKMS modules), `/var/cache/steamify/kernel` (the old
+kernel pin's packages), and `*.bak-gamescope-wizard` backups next to the
+system files that were edited (that name stays: it's how they're found again).
+
+Before 2.5.0 the home folder paths used the project's old name
+(`cachyos-gamescope-boot`). `migrate_layout` (`lib/state.sh`) moves them at
+every start of a newer version, once, and leaves symlinks under the old names
+so an older release still finds the same state; it fixes the paths in the
+launcher entries and the update check's unit, and merges when both exist.
