/**
 * Reveals are scoped to html.anim, set by a one-line script in the head.
 * If that script never runs, nothing is ever hidden and the page reads as
 * plain prerendered HTML — the failure mode is "no animation", never
 * "no content".
 *
 * do9.in — the styles the React bundle used to apply at runtime.
 *
 * Loaded after the main stylesheet, which supplies every token used here
 * (--color-ink, --color-rule and the rest). Content is legible without
 * this file; it adds motion, the mobile sheet and the enquiry dialog.
