Every page of a Rails app opens as a window in endlessly scrolling column strips, one strip per workspace. Pages say how they want to be shown (size, modal, full width, workspace, reuse key); ⌘K and a drop-down terminal run the same fuzzy-matched command tree; a keymap with a configurable modifier (⌘ in a native shell) and optional Blender-style hover keys drive the windows. Ghostty colour themes and Unsplash wallpapers included. The host app keeps its own controllers and views.
