- text-shadow default: updated to outline-style multi-shadow
- anki: reset ai model/prompt, imageMaxWidth/Height, animatedMaxHeight to 0; isLapis defaults
- troubleshooting: log default warn (not info), css["font-size"] usage
- shortcuts: add W markWatchedKey; clarify keybindings vs built-in overlay actions
- websocket: clarify all services off by default, fix enabled semantics
- usage: --anilist → --anilist-setup
