Add Region & Language, and answer "what am I running on" in About

More GNOME Settings parity. Region & Language is new. The locale is localectl's, and Panama stores no copy of it -- there is exactly one system locale, so a preference here would be a second source of truth that drifts the moment anything else changes it. Codes are resolved against iso-codes into "Portuguese (Brazil)" the way GNOME does, with the code kept visible because it is what actually gets written and someone choosing between two Spanish variants needs to see it. Changing it is privileged and only applies to programs started afterwards, so the page says a sign-out is needed rather than claiming the new language is in use. The service is called SystemLocale, not Locale: QML has a built-in Locale value type that silently shadows a singleton of that name, and every binding then reads properties off the wrong thing. The page rendered empty with nothing but "cannot read property of undefined" to explain it. About now answers what GNOME's About answers -- model, processor, memory, disk, OS, kernel, windowing system -- where before it listed only Panama's own component versions. Graphics is joined from GraphicsDevices rather than read again, because two readouts of the same hardware are two things that can disagree. Placeholder DMI strings ("To Be Filled By O.E.M.") are filtered out, and unreadable facts are omitted rather than shown as "Unknown". The Fedora hand-off card was one row listing five subjects that opened the network panel regardless. Naming a panel and then not opening it reads as a broken button rather than a deliberate hand-off. Each subject now opens the panel that owns it, and openGnomePanel takes an optional subpage so "Users" reaches System's users page the way GNOME's own desktop entry does, instead of dropping the user on System's front page. Printers and online accounts are not repeated here; they stay with the network hardware on Network & Devices. One bug this surfaced, caught by the hyprland write contract: the Lua config key and the hyprctl option name genuinely differ for tap to click. hl.config wants input.touchpad.tap_to_click; getoption answers to input:touchpad:tap-to-click. Either spelling used for both fails -- a hyphen is not a Lua identifier, and the underscored name is not a known option -- which is what the schema's two separate fields are for.

+// Region & Language.
+//
+// GNOME keeps language and formats under System; the setting itself is the
+// machine's locale, which localectl owns. Panama does not store a copy of it --
+// there is exactly one system locale and localectl is where it lives, so a
+// preference here would be a second source of truth that drifts the moment
+// anything else changes it.
+//
+// Keyboard layout is deliberately not repeated here even though GNOME groups it
+// with region. It is a compositor setting that applies instantly, it lives on
+// the Keyboard page with the rest of the typing settings, and showing it twice
+// invites the two views to disagree.
