Pull request overview

A collection of small fixes and cleanups across rendering, UI, and IO flows (including improved tree-shaking in the heightmap renderer, safer exports, and clearer user-facing messages).

Changes:

• Refactor draw-heightmap to avoid d3 namespace access and use an explicit curve map for better tree-shaking.
• Improve robustness/UX of IO flows (save/load/export): better error messages, async handling, autosave feedback, URL-load timeout handling.
• Miscellaneous polish: optional chaining cleanup, typo fixes, formatting/readability improvements, and removal of outdated UI text.
