	work — professional meetings, standups, sprints, tech decisions (no action needed)
	personal — personal life, family, hobbies, travel, health, movies
	reference — articles, tips, cheatsheets, resources saved for later

	2. Mentions meetings, standup, sprint, backend, frontend, team, manager → work
	3. Mentions family, hobby, movie, travel, health, weekend → personal
	4. Everything else (articles, tips, guides, cheatsheets) → reference
