/*
 * "Ask your AI" (Brand Bible 1.3 §7.10).
 * A quiet 48 px graphite tile with a spark in the page's service accent: it reads as
 * AI help, not as a filled contact button. Its label slides out on hover or keyboard
 * focus, and once per page at a natural reading pause. The chooser is a popover
 * on wide screens and a bottom sheet on phones. Motion uses transform and opacity
 * only and is removed for reduced-motion users.
