======================
BANDS
======================

The band vocabulary the main site's newer pages are built from: the home
page, Meet the Cast, the tools page, the articles index and the reading
page, the four tool pages and the AI disclaimer. A page is a stack of bands, each
carrying the section colour code from BRANDING.md (crimson for the campaign,
purple for the channel, blue for the tools), with a band header of eyebrow,
title, one line of copy and an "all of it" link on the right.

Every colour is a styles.css token, apart from the three light tints used
for coloured text on a dark ground, which have no token: #ff7d9e (crimson),
#b98cff (purple) and #8fa0ff (blue), and the two greys for secondary copy
on a light band, #5a5670 and #8a8599. BRANDING.md lists them.

Bare <section> gets styles.css's 4rem padding and overflow:hidden, so a band
sets its own padding and overflow with .band.

share: the home hero's night ground (--night to --night-deep) under the

the eyebrow, pills and links take the dark-ground tints above. The home,
