/* ============================================================
   WhatsApp-style number popup (assets/wa-popup.js), long landing.
   Same design as Durham and Horizon; the /go flow carries its own
   copy in flow/src/flow/wa-popup.css.
   Colours follow WhatsApp's own UI, not the school palette:
   the parent should recognise the chat before reading it.
