Subject: [PATCH] Deploy-base-aware asset URLs; live at partly.party/toastsim
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Absolute '/assets/...' paths 404 under the /toastsim/ subpath (and the
root /assets/ URL is another game's — returns 200 with wrong content,
the classic partly.party trap). assetUrl() prefixes BASE_URL inside
loadProp + the four direct loads (bench/backdrop textures, title art,
judge portraits). Verified live: JS application/javascript, toaster.glb
4.5MB binary, title_art image/png, title screen renders.
