/*
   Header item and banner that offer the NeuraCore Chat browser extension.

   Both are Core Violet / Signal Cyan - the extension's own palette (see
   NeuraCore.Extension/README.md), not the portal's WhatsApp green. What is being advertised is the
   extension, and a green card would read as part of the chat rather than as the thing that opens it.

   Nothing here is visible until extension-promo.js has decided which state to show: the markup ships
   with .d-none on both, so a browser that cannot install it, or one that already has it, never
   flashes an install prompt.

/* ---- header item ---------------------------------------------------------------------------- */

/* The dot sits where the bell's unread count sits, so the two read as one row of status. It takes
   the theme's accent from .bg-primary in the markup rather than the extension's cyan: on the dark
   header a second, unrelated colour next to the blue unread badge reads as a fault rather than as a
   prompt. No ring and no pulse - it is a marker on a button, not an alert.

   It stays while the extension is missing, where the banner does not: unlike the banner it is not an
   interruption, and a button with no marker looks like it does nothing. */
