 * Install section — 5 installation methods as a tab group.
 * Desktop: tabs laid out as a horizontal pill bar.
 * Mobile: collapses into an accordion (each tab becomes expandable
 * panel).
 *
 * Each panel contains a terminal-style command block with its own
 * copy-to-clipboard button. Commands use per-line prompt coloring
 * for the "$ " marker.
