/*
 * Pitié "Contexte" timeline page styles.

 * first (design tokens) — this file no longer redeclares --pitie-* tokens,
 * closing the DA drift that previously existed between this page and the
 * main app (this page also used to fall back to a non-Inter font because
 * it never loaded the Google Fonts link; context.html now does).
 * Keyframe names are prefixed pitieContext* to avoid colliding with a host
 * page's own @keyframes of the same generic name (fadeInUp, bounce, ...).
