The unified Gateways settings page (from the recent settings merge) still carried the legacy per-profile gateway-override machinery: an "Applies to" profile-chip scope switcher, a scope state machine threaded through load/ save/test/sign-in paths, inherit-mode ModeCard variants, and an SSH remote-profile mapping row. The page is machine-level gateway management: it decides which gateway backends this desktop can connect to, and profiles are discovered FROM the connected gateways. It must not be profile-scoped. - Delete the scope chips section, ScopeChip component, and the scope/setScope state; every scope-conditional collapses to its global (scope === null) branch. getConnectionConfig/save/apply/test/sign-in are all unscoped now. - ModeCard local card always renders the local title/desc (inherit variants gone); SSH remote-profile mapping row removed. - i18n: drop now-unused gateway keys (appliesTo, allProfiles, defaultConnection, profileConnection, inheritTitle, inheritDesc, sshRemoteProfileTitle, sshRemoteProfileDesc) from types.ts and en/zh/ zh-hant/ja/ar in sync; rewrite the gateway intro in each locale to say connections are machine-level and profiles come from gateways. - Tests: replace the scope-switching component tests with a machine-level assertion (loads getConnectionConfig(null), never a profile scope, no scope UI rendered). - Docs: update desktop.md and multi-connection-desktop.md wording — gateway connections are machine-level; per-profile backend routing continues via the profile rail / session source surfaces, not the settings page. The electron main-process per-profile override mechanism (getConnectionConfig(profileName), route map) and the profile-rail connect flows are intentionally untouched; only the settings page loses the affordance.
