/*
 * CaVaToi — one stylesheet, no build step, no framework.
 *
 * Two things drive every choice here: the people filling in the daily
 * questionnaire may be old, tired or shaky, and the host gives us 1 GB. So:
 * large touch targets, real text sizes, high contrast, and no dependencies.
 *
 * [data-a11y="1"] on <html> turns on reinforced accessibility: everything grows
 * and contrast goes up. It is a scale factor, not a separate stylesheet.
