/*
 * emularity-maw.css — myabandonware.com branding for the Emularity splash.
 *
 * Ported from the V3 site (www3 game.scss). The stock Emularity styles its
 * splash inline from loader.js; passing `hasCustomCSS: true` to
 * `emulator.start(...)` makes it skip those inline styles and defer to the
 * classes below instead. Include this stylesheet and pass that flag to get the
 * MAW look: a spinning branded logo, a top title bar, and a bottom progress bar.
 *
 * The splash element (`.emularity-splash-screen`) is appended to the canvas's
 * parent, so give that parent `position: relative` for the overlay to sit over
 * the canvas. The per-game screenshot background is set by the host app on the
 * splash element itself — it is not styled here.
