/* build/float_continue.css
 * Floating "Continue / Next" button pattern shared across the Arc-Tuning flow.
 * Any button with class="fc-target" sticks to the bottom-right of the
 * viewport so the user never has to scroll to find their next action.
 *
 * When the button is disabled (real disabled, aria-disabled, or .is-disabled)
 * it appears grayed. Clicking a disabled fc-target triggers float_continue.js
 * to flash the required fields (selector in data-fc-required).
