Day Seven

Adding clearer purpose and structure to docs.

Also made some small but meaningful updates across the Projects and Blog pages.

Updates

• Added an Atomic Design page and wired it into the docs sidebar.
• Rewrote the docs Welcome page so the purpose is clear.
• Updated the Starlight header config (title + social links).
• Built out the Projects landing page with two project cards and status pills.
• Updated blog date formatting to include weekday (short form) and added the date to post pages.
• Added work-in-progress descriptions to Typography and Button docs pages.
