/* Callout
 *
 * An inline message attached to the thing it is about. Four tones:
 *   info     neutral context
 *   success  something completed
 *   warning  something needs attention soon
 *   danger   something is wrong or destructive
 *
 * Plus one product-specific use that earns its own variant:
 *   .callout--upgrade   the plan-limit prompt (pricing.md)
 *
 * Tone is never carried by colour alone — every variant has an icon glyph and
 * the message text states the situation. A colour-blind user, a greyscale
 * screenshot, and a screen reader all get the same information.
 *
 * Live announcements: use role="status" for info/success, role="alert" for
 * warning/danger. Do not put role="alert" on something rendered on page load —
 * it interrupts. Only on content that appears in response to an action.
