The ground shades from purple into a medium blue

Matches ios!144, value for value: #D6C2F4 to #82ABE0 top down, and
#1C1036 to #071426 in dark mode.

⚠️ The blue end is not decoration. The mark is a blue globe with an orange
flame, and a purple-only app left the icon as the odd one out — the one thing on
screen from a different palette. Shading into blue puts the icon's own colour on
the page instead of beside it.

🔴 SecondaryText moves again, for the third step in a row: #413A4D read 4.6:1 on
the new bottom stop, inside the margin rather than clear of it. #332E3D reads
5.5:1. The bottom stop always binds and it is where the explanatory copy sits.

The palette test checks all of it — both ends of both gradients, and that the
two platforms still agree. 4 tests, 0 failures, read from the results XML with
its age printed: an earlier run of this suite reported two failures that were
stale output from a build that had not recompiled.
