/*
 * Round 78 - Document Templates: language tabs, category sections, item tables, "Auto calculate", the free-download
 * counter and the sign-in / watermark pop-ups, plus the motion for all of it.
 *
 * Motion is decorative: everything that moves sits inside `prefers-reduced-motion: no-preference`, and content is never
 * hidden unless doc_templates.js has run (it adds .dt-anim / .is-in itself).
 *
 * RULE (same as blog_motion.css): never put a transform / filter / perspective / fill-mode animation on <body> or on an
 * ancestor of a position:fixed pop-up - it would become the containing block of the fixed element and the pop-up would open
 * off-centre. The pop-ups (.dtq-modal) are appended to <body>; only the overlay itself and its leaf box animate, and the
 * overlay animation has no fill-mode.
