+// Restauració del canvas en wasm/Emscripten
+// ============================================================================
+//
+// Problema: SDL3 + Emscripten no notifica de manera fiable els canvis de mida
+// del canvas HTML. En concret:
+//   - SDL_EVENT_WINDOW_LEAVE_FULLSCREEN no s'emet quan l'usuari surt de
+//     fullscreen amb Esc/F11 (libsdl-org/SDL#13300).
+//   - SDL_EVENT_WINDOW_PIXEL_SIZE_CHANGED i SDL_EVENT_DISPLAY_ORIENTATION
+//     tampoc es disparen de manera fiable (libsdl-org/SDL#11389).
+//   - Resultat: en sortir de fullscreen el canvas queda a la mida correcta
+//     però SDL encara creu que està en fullscreen amb la resolució anterior,
+//     i el joc es veu minúscul fins que l'usuari força un refresh manual
+//     (p. ex., canviant el mode d'escalat amb F7).
+//
+// Solució: registrem callbacks natius d'Emscripten (fullscreenchange,
+// orientationchange) que re-sincronitzen SDL amb l'estat real del navegador.
+// NO registrem resize callback: en mòbil el scroll fa que el navegador oculti/
+// mostri la barra d'URL, disparant un resize del DOM per cada scroll.
+// Tots delegen en Screen::handleCanvasResized(), que crida setVideoMode()
+// amb l'estat de fullscreen actualitzat — això és el que realment restaura
+// la finestra SDL perquè dins setVideoMode es crida SDL_SetWindowFullscreen,
+// que és imprescindible per treure SDL del seu estat intern de fullscreen.
+//
+// Els callbacks diferixen la feina amb emscripten_async_call(0ms) perquè
+// quan l'event es dispara el navegador encara no ha acabat de redimensionar
+// el canvas: llegir la mida en aquest instant donaria un valor obsolet.
+// Posposar al següent tick del event loop garanteix que el canvas ja està
+// estable quan actuem.
