From aec12ff6c553888bde82958a0c479e7255dce83c Mon Sep 17 00:00:00 2001 From: Andriy Oblivantsev Date: Mon, 2 Mar 2026 22:48:19 +0000 Subject: [PATCH] Upgrade vendored Three.js and MapLibre to latest releases. This updates Three.js to 0.183.2 and MapLibre GL to 5.19.0, and rewires GLTFLoader utility imports to local vendored modules for browser module compatibility.
