feat: a shorter page on phones

On a phone the homepage was about 29 screens long; it is now about 22.
The desktop layout is unchanged to the pixel.

Lists of equal items (automation notes, project fit, principles, reasons for
a web presentation, by hand vs. automated) are swiped through side by side
(SwipeRow) instead of stacked. The four service cards form a compact 2x2
grid, step lists spell out only the current step, the workflow legend and
the per-project task lists are left out, and sections use less padding.
