/* Chimera AI pre-assessment widget. Defaults mirror the landing page tokens (web/landing/index.html).
   Theme it from the host page by setting any of these custom properties on :root, a parent or #chimera-assessment:
     --ca-font  --ca-font-mono  --ca-bg  --ca-surface  --ca-fg  --ca-muted  --ca-border
     --ca-primary  --ca-primary-fg  --ca-accent  --ca-accent-fg  --ca-user  --ca-user-fg  --ca-assistant  --ca-assistant-fg
     --ca-focus  --ca-radius  --ca-radius-sm  --ca-shadow  --ca-offset  --ca-z
   Dark mode (prefers-color-scheme: dark, or data-theme="dark" on the root; data-theme="light" opts out) reads the
   same names with a -dark suffix (e.g. --ca-bg-dark), falling back to built-in dark values. */
