- Main app swapped from warm cream/sage to cool slate light theme with
blue accent; dark-* tokens and text-white/gray overrides remapped in
tailwind.config.js and index.css
- Calendar events now render in Google's 11-color palette (Tomato through
Graphite), deterministically hashed from the event summary so the same
event always gets the same color
- PhotoFrame uses object-contain (whole photo shown, letterboxed) instead
of object-cover; clock + date moved to lower-right, same white color,
text-shadow for readability over any photo
- EMAIL_UPLOAD.md / PHOTO_FRAME.md / iCloud sync script and systemd timer
remain unchanged
