/* Local modification (this whole file — see specs/html5-snake/design.md): every originally-bare
   selector ("body"/"h1"/"p"/"canvas") is now scoped under "#app", this game's own exclusive
   mount root in both the standalone page (games/html5-snake/index.html) and the Camila-hosted
   dashboard tab (../../dashboard-html5-snake.inc.php) — unscoped, "body { background-color }"
   alone would have recolored the whole surrounding Camila page, not just this game's own area.
   ":where(#app)" not "#app" on the bare-selector rules specifically, matching the fix
   specs/hextris/design.md documents for the exact same problem there: a plain "#app canvas"
   carries an ID selector's specificity that upstream's own bare "canvas" never had, which could
   silently outrank some other rule meant to win against it. There's nothing else in this small a
   stylesheet that actually depends on losing to a more specific rule, but using ":where()" here
   too costs nothing and avoids having to re-derive that reasoning from scratch if this file ever
   grows. The original upstream page also styled <h1>/<p> (a title and some instructional text) —
   not carried over here, since this integration doesn't render that chrome at all (see
   index.html's own comment) — only "body"/"canvas" remain to scope. */
