/* ============================================================================
   FILE: assets/ask.css
   PURPOSE: Look of the "Ask" widget (assets/ask.js). Uses the site's tokens from
     styles.css (--ink, --bone, --ember, --line ...) and falls back to the same
     values if they are not defined, so it also works on a page without styles.css.

   RULES THIS FILE FOLLOWS
     - Logical properties only (inset-inline-end, padding-inline, margin-block ...),
       so a right-to-left page mirrors correctly.
     - Motion only under prefers-reduced-motion: no-preference.
     - Every target is at least 44px tall. Text contrast is at least 4.5:1 on its ground
       (bone #efeadf and muted #a8a294 on #100f0d; ember-ink on ember).
     - Sits under the skip link (z-index 200) and above the grain layer (90).
