Read HID++ feature 0x4540 KeyboardLayout to detect the device's country
code, then route the per-key painter to a matching regional layout.
Changes:
- lib/logitech_receiver/hidpp20.py: new get_keyboard_layout() returning the
HID Usage Table country code from feature 0x4540's first response byte.
- lib/logitech_receiver/device.py: lazy device.keyboard_layout property,
guarded by feature presence so devices without 0x4540 don't pay a query
cost on access.
- lib/solaar/ui/perkey/control.py: thread the country code into the editor
hint dict.
- lib/solaar/ui/perkey/layouts/_keyboard_base.py (new): factor out the
function row, nav cluster, and numpad block as shared building blocks.
Two main-block variants (ANSI with row 2 col 13 backslash, ISO without)
cover all five regions. build_layout() applies per-zone label overrides
on top of either main block.
- lib/solaar/ui/perkey/layouts/keyboard_ansi.py: refactored to use the
builder; same LAYOUT_FULL/LAYOUT_TKL exports.
- lib/solaar/ui/perkey/layouts/keyboard_iso_qwerty.py (new): UK English
ISO. Same shape as DE/FR/JIS but no label overrides.
- lib/solaar/ui/perkey/layouts/keyboard_iso_qwertz.py (new): DE/Swiss --
Y/Z swap, Ü/Ö/Ä/ß placement.
- lib/solaar/ui/perkey/layouts/keyboard_iso_azerty.py (new): FR -- A↔Q,
W↔Z, French digit-row symbols, M repositioning.
- lib/solaar/ui/perkey/layouts/keyboard_jis.py (new): JP -- @ / [ / :
bracket-row relabels.
- lib/solaar/ui/perkey/layouts/__init__.py: country-code-aware matchers,
five families × two sizes (full/TKL). Defaults to ANSI when 0x4540 is
unsupported or returns an unknown code.
POUND, ISO_BACKSLASH, and the L-shape Enter top half (zone 46) are
intentionally omitted from the ISO layouts -- same coverage as OpenRGB.
ABNT2 (Brazilian) deferred until a confirmed Logitech BR RGB device shows
up; adding it later is one new layout file plus a country-code entry.
Also fix copyright headers on all new lib/solaar/ui/perkey/ files: the
files were created in 2026, not 2024 as the headers said.
