Editorial methodology
- This roundup focuses on Slack admin and people-ops needs: headshots, culture reactions, onboarding rituals, and Slack's tighter file-size rules.
- Tools are compared by practical workflow fit rather than by invented numerical scores.
- The best Slack tool is the one that can produce useful reacji from real team assets without requiring a full design detour.
