/*
 * FIX (12 Aug 2026 — reported bug): the launcher sat at a fixed
 * bottom:22px/right:22px, z-index 1600 — ABOVE the sticky compare tray
 * (.compare-bar, z-index 500), which also docks to the bottom-right with
 * its Compare Now / Clear buttons. Whenever both were visible at once
 * (any page with items in the comparison tray), the launcher physically
 * covered those two buttons, making them unclickable — exactly the
 * "unable to click Clear/Compare" bug reported on products.php,
 * compare.php, and index.php.
 *
 * Fix: app.js now toggles a `compare-bar-visible` class on <body> in
 * lockstep with the compare bar's own `.show` class (same 4 call sites
 * that already show/hide the bar). When present, the launcher is pushed
 * up above the bar's height instead of overlapping it — the same
 * approach this stylesheet already uses for the floating WhatsApp button
 * (.float-wa, bottom:100px, for this exact same reason).
