last one for this round, added a theme switcher to the desktop. there’s a new [*] button in the taskbar that cycles through three color schemes: ember (the original orange, default), phosphor (green, classic crt terminal look), and cyber (blue). clicking it swaps the accent color across the whole desktop. window borders, highlights, the terminal cursor, and even the living mascot’s glowing eye all shift to match, since they were already built on a shared accent
variable.

it resets back to ember on reload, so you always start from the default look.

architecture-wise this was a clean one to slot in. the theme logic is a small standalone module (just a list of themes and a “next theme” function), same pattern as the window manager and mascot logic, so it’s unit tested without needing a browser.
