# Script:        chat.css           (stylesheet, loaded by the public pages: index.html, about, gallery, greatgallery,
#                                    wisdom, patreon, bookoffaces, portals, privacy and 404)
# Created by:    Matthew Boucher
# Start date:    2026-10-16
# Location:      <project root>/frontend/css/chat.css   (main script: <project root>/aiacolyte.py; subscripts: <project root>/subscripts/aiacolyte/)
# Description:   The look of the "Ask the Acolyte" chat widget: the round button in the bottom-right corner,
#                the chat panel (header with the "admins only (testing)" tag, the conversation, the typing
#                indicator, the message box with its character counter and the privacy notice) in the site's
#                dark arcane style: candlelit ink, conjured gold and the arcane blue of the AI half of the
#                magic. On small screens the panel fills the width (and most of the height); with
#                prefers-reduced-motion every animation and transition is switched off. Every class starts
#                with lchat- so it cannot clash with a page's own styles. Works with chat.js (which builds
#                the widget) and uses the colour tokens and fonts from styles.css, with fallbacks.
# Reads:         the colour tokens and fonts from styles.css
# Writes:        nothing
# Sensitive:     none needed
# Arguments:     none (a stylesheet cannot take flags); aiacolyte.py --checkup confirms it is in place
