- Cycle ring: the fixed 120 px shrink-0 ring overflowed grid cells on
360 px Android widths. It now caps at its target size but is free to
shrink to fill its cell, so it never pushes the page wider than the
viewport.
- Cycle tab strip: the four long German labels overflowed the equal-width
flex-1 cells and forced a horizontal scroll at 375 px. Below sm the
triggers size to their content (text-xs, no flex-1) and scroll cleanly;
from sm up they reclaim the equal-width layout.
- Calendar day cells: bump the 40 px min-height to 44 px to clear the
mobile tap-target floor.
- Add a Pixel-5 spec asserting no horizontal scroll on /insights and
/cycle plus the calendar tap-target floor.
The cycle view also now feeds the profile's typical lengths into the
wheel so a low-data tracker gets the canonical four-phase ring.
