   Microsoft Teams mock  ·  Invisible
   ────────────────────────────────────────────────────────────────────────
   A self-contained, realistic Teams chat surface so the "Slack, Teams, email"
   promise has a Teams proof to point at. Mirrors the polish of the existing
   .coach-* Slack mock but stands alone (no shared chrome) so it can drop into
   any page that ships this stylesheet — no JS, transform/opacity only.

   Recognizable Teams chrome: the Fluent indigo accent (#5b5fc7), the official
   Teams hexagon mark (assets/logos/teams.svg), a left rail of app icons, a
   message from the Invisible app, a reaction, and the Teams compose box.
   Tokens (--white/--ink/--line/--subtle/--body-color) come from styles.css.
