 Every setting lives in `~/.config/amane/config.toml`: sizes, timings, text sizes, colours, poll intervals, equalizer presets and bands, the hotspot profile, the extra Sound output. The shell writes the file with every setting and its explanation the first time it starts (moving `cover_colors`, `transition_ms`, `hotspot` and `extra_output` over from an old `shell.conf`, which it no longer reads). Saving the file applies it at once; a line left out takes its default, and a line the shell can't use is listed at the top of the config window. The font and the cava bar count take effect on restart.
 
-The config window edits the same file: Settings at the foot of the control centre, or `amane ipc call config toggle`. It is a normal window with a page per part of the shell, a page per Hyprland category, and a search over everything. Numbers with a range get a slider and a field, switches toggle, colours show a swatch; a typed value applies on Enter. Reset brings back the default.
