Streak Badge Icon Ideas

Default icon: Flame (current choice)
- Why: instantly communicates streak momentum.
- Keep compact (14px) and lightweight in header.
Alternative icons to test:
- Zap for a sharper "energy" feeling.
- CalendarCheck for a more neutral productivity tone.
- Trophy for milestone-focused streak celebration.
Visual variants to evaluate:
- Color by state:
  - Active streak (orange)
  - No streak (gray)
- Optional pulse animation only on milestone days (7, 30, 100).
- Optional tooltip copy:
  - "Read today to keep your streak alive."

Reintroduce a redesigned Heatmap mode in Reading activity after visual cleanup.
- Keep it optional in the activity view switch.
- Improve density/contrast so it feels lighter and less crowded.
