All four use V3's highlighted-row pattern (crimson-wash bg + left border). Each experiments with a different right-side indicator — from minimal to informational.
Just the count in a small crimson circle. No words. Clean, precise, universally understood.
The word 'Updated' in small caps. No count. Institutional tone — feels like a status indicator, not a notification.
No text at all. A 5px crimson dot on the right edge. Maximum restraint — the highlighted row does the talking, the dot is just a confirmation.
Mono-set '+3 added' — reads like a changelog entry. Precise and informational without being chatty. Shows quantity with professional tone.
