   AMM WEBSITES — CLASS-FINDER CHATBOT WIDGET
   ------------------------------------------------------------------
   A lead-qualification chat widget: a few quick questions, then a
   Book Now link or a "call me back" handoff. Opens as a popup
   anchored near the launcher on desktop, full-screen below 480px.

   Deliberately styled off the SITE's own tokens (--brand/--brand-bright/
   --brand-deep, --ink-2/--panel/--paper/--grey/--line, --f-display/
   --f-body) rather than a separate colour system, so re-colouring the
   site for a new client — or picking a different accent via the demo
   picker — re-colours this widget too, with zero widget-specific
   edits. Only exception: --ink-on-accent below, a FIXED dark value
   (not the theme-flipping --ink) used wherever text/an icon sits
   directly on --brand — see the comment on that variable for why.
   ================================================================ */

    /* Fixed near-black for text/icons placed directly on --brand. --ink flips to
     near-white in the light theme, which would break contrast on the (always
     mid-to-bright) accent colours — this mirrors the site's own --on-dark
     pattern (a token that deliberately does NOT follow the theme), just the
     dark-on-bright-accent equivalent instead of light-on-dark-photo. */
