/* Floating contact buttons (markup and behaviour: includes/floating-menu.html).
 *
 * WhatsApp and Email side by side at the bottom centre, Email as a round
 * envelope icon. Same look as the two
 * buttons in the homepage hero (.tc-hero__btn--wa and --ghost), made smaller
 * and thinner: 2.5rem tall instead of 3.25rem. The hero's ghost button is
 * white on a dark photo, which would vanish over white sections, so Email
 * here is the same frosted glass in navy.
 * Standalone: no Tailwind classes, every class starts with "tsc-float-".
 * Sits below the navbar (z-index 50).
