/*
 * Toast position/style variants and the corner-spinner loading indicator.
 *
 * Deliberately a small, hand-written, standalone stylesheet rather than an addition to
 * assets/css/tailwind.css: that file is generated by `npm run css:build` from
 * assets/css/tailwind.css (the source), and editing the source requires running that
 * build before anything here would take effect. Keeping this separate means the
 * System UI Optimizer's toast/spinner settings work immediately, with no build step.
 *
 * Applied to the existing .toast-stack (views/layout_bottom.php) and #page-progress
 * (views/layout_top.php) elements — this file only adds position/style *variants* on
 * top of their current base rules in tailwind.css, it does not redefine them.
