The horizontal Timeline is built for a 13-inch screen. On a phone, it crushed the chronotype zones into unreadable stripes. The day became a barcode.

G T on mobile now renders vertically. Top of the screen is dawn, bottom is dusk, chronotype zones fill the full width, and particles sit as labeled rows — task name on the left, duration on the right. Opening the view auto-scrolls to now, so the present is centered before you scroll. Desktop is unchanged. Mobile follows the device, not the desktop card metaphor.

#What changed

Vertical mobile timeline — replaces the horizontal track below 768px
Full-width chronotype zones — no more squeezed stripes
Labeled particle rows — task name and duration, read at a glance
Auto-scroll to now — the present centers on open for today
Desktop unchanged — horizontal track stays at md and above

The device decides the orientation. The day stays the day.
