 - [x] T18 Merge the official region-profile PRs (omarchy #13690, #14399; omarchy-iso #206, #236) and align to them: region code `cn` in `/etc/omarchy/region`, China files under `default/regions/cn/`, pacman rendered by `omarchy-apply-pacman` (`.cn` twins first, USTC fallback, ArchLinuxCN with its keyring), offline timezone `Asia/Shanghai`; the ISO keeps the first-screen region choice and bundles the China profile, `--region cn` preselects China
 
 - [x] T19 Merge the reworked #13690 (timezone-derived region) and align: `mirrorlist-<channel>.prepend` and `timezones` replace `servers.sed`, `mirrorlist.append` and `timezone`; drop #14399's timezone preselection (closed upstream); `install/config/region.sh` reads `/etc/omarchy/region` instead of `OMARCHY_REGION`; drop the dead `china` rename migration
-- [ ] T20 Merge #14433 (input methods) and remove Rime: packages, `install/user/region.sh`, the Rime steps in `install/config/region.sh` and `omarchy-region`

 - [ ] T22 omarchy-pkgs: revert the `rime-ice-installer` package
 - [ ] T23 omarchy-iso: merge upstream `quattro` (#237) and #241; remove the region screen, `--region`, `prepare-region.sh`, the region skel, Rime bundling and its pin
