 * scrolls: --fmt-intro-p, the shrink progress from 0 (top of page) to 1, and
 * --fmt-intro-fade, the same progress eased into the window where the two
 * logos cross-fade. The root, not the header, because the page content next to
 * the header needs them too and custom properties only reach descendants.
 * Every size below is a straight line between the design's tall and slim
 * header (src-v2/logo-intro.jsx, src-v2/mobile.jsx).
