/* ============================================================
   Chat Widget Launcher — modeled on the LEO chat widget
   Palette (LEO obsidian theme):
     #0a0a0f / #12121a / #1a1a24 / #252532  (dark surfaces)
     #4f46e5 (indigo-neon)  #818cf8 (indigo-glow)  #7c3aed
   The per-form `--cw-border-color` and `--cw-border-radius`
   variables (set inline by the launcher root element) still
   override the LEO defaults so each chatflow can match the
   site's branding.
