Toggle
A pill that stays down when pressed: one click turns it on, the next turns it off. It carries aria-pressed, and its label never changes with its state; the fill says which state it is in. Entities' filters, ask's smart replies, search's mode, a group's roll up.
solid fills with --toggle-on (--fill-accent in both themes) and drops its label to --text-on-accent when on: a filter that narrows what you see. soft (.chip-toggle.soft) only lifts to a --bg-muted fill in --text-default: a mode switch whose two states are both ordinary, like search's meaning / exact text.
Entities' filter row, live: click to turn each on and off. Search's mode is the one toggle whose label changes, because its two states are two named modes rather than on and off.
