Give the content pages the landing's look

Moving from the landing to a page read as changing sites: a narrow
centred column on a flat background, light headings, no cards. The
page now opens like the landing's hero — the same two lights, the same
left edge as the logo, a bold title with the excerpt as its lead — and
the body's headings are bold like every section title on the landing.

The lights move into a shared mixin (ui/_lights.scss) so the hero and
the pages cannot drift apart. On a page they sit on the whole <main>
with `overflow: clip`, so they fade out on their own instead of ending
in a hard edge right where the text starts, and `clip` rather than
`hidden` keeps the sticky side column working.

A side column keeps a page from being a dead end: "keep reading" cards
for the other pages, its own category first, and a card to get in
touch, both on the landing's card surface.
