Prior attempts (raw JSON, \u007B / \u007D Unicode escapes) both got
truncated in the deployed build: Rspack's html-plugin decodes Unicode
escapes BEFORE running its template engine, so by the time the engine
sees the script body both raw and escaped '{z}' look identical and
get swallowed. Result: injected MAP_TILE_URL stopped at '/tile/{z'
and the client fell back to the default URL.
Serialize the env payload to base64 instead and decode it at runtime
with `JSON.parse(atob("..."))`. The base64 alphabet is A–Z/a–z/0–9/+//
/= — no braces for any template engine to grab. Switch the assign
target to `Object.create(null)` to keep the source brace-free; the
resulting runtime object is indistinguishable for getEnv().
