/* =========================================================
   Info-tip: small circular `!` help button + tooltip bubble
   =========================================================

   Rolled out portal-wide next to dashboard widget headers,
   tab/tool titles, and field labels so new users can get a
   one-sentence explanation of what an element does.

   Design constraints (firm):
   - Light theme only — no dark backgrounds.
   - Must not disrupt flex/grid layouts — uses inline-flex.
   - Bubble must open on hover AND keyboard focus (a11y).
   - Button is 18–20 px so it reads as "help" not "delete".
