-- Follow-up to gen2_pokegear_native_colors_test.lua's "keep the gear
-- vanilla" fix: CLASSIC swept the native-coloured gear for free, so this
-- extends the same whole-panel tint to a picked custom COLORS ramp, with
-- Pokegear.CUSTOM_RAMP_FILM = false as an easy revert.
--
-- No real shader/asset loads headless, so this isolates drawPanel()'s new
-- branch with a minimal fake self, same "stub the rest, assert the seam"
-- approach as the TrainerCard drawPanel() test.
