- Updated `DEFAULT_TRUSTED_MUTE_HIDE_THRESHOLD` in `config/instance-config.js` from 1 to 20.
- Updated `tests/moderation/trusted-mute-lists.test.mjs` to explicitly override the threshold to 1 for tests verifying the hide mechanism.
- Updated documentation (`docs/moderation/*.md`, `docs/instance-config.md`, `content/community-guidelines.md`) to reflect the new default and upstream examples.
- Verified that existing blurring logic in `js/feedEngine/stages.js` and `js/ui/components/VideoCard.js` handles the intermediate state (1-19 mutes) correctly.
