Add now page and activity timeline to the public site

[johnnyhuy]

Your weekly notes call out both a /now page and a timeline of previous site designs as useful lightweight additions to the portfolio.

Starter scope:

• add a simple now page
• add a yearly or design-history timeline
• keep it lightweight enough to maintain regularly
