/*
 * FM-12 Toggle switch — app/components/ui/toggle_component.rb
 *
 * Built on a real <input type="checkbox" role="switch">, track and knob
 * drawn via a sibling combinator exactly like checkbox.css/radio.css — no
 * JS needed, native click/keyboard/label-click behaviour for free.
 *
 * Never used for a destructive action — a toggle implies a reversible
 * preference, not a one-way action (see spec FM-12).
 *
 * Token vars only — enforced by test/lint/css_token_lint_test.rb.
