The real reason Mesh:Tool ignored the theme: set_darkmode() runs inside
restore_space(), which only fires on the non-CMMS boot path
(motoClient 'ready' -> restore_space). The CMMS path
(motoClient 'ready' -> cmms_load_from_url) never called it, so #app never
got the .dark class and the #app:not(.dark) light CSS always won ->
white, regardless of theme. Now cmms_load_from_url()'s finally block
calls set_darkmode(config.dark ?? true).
