# Script:        styles-hero.css     (stylesheet, part of styles.css, loaded by frontend/index.html)
# Version:       1.01
# Created by:    Matthew Boucher
# Start date:    2026-09-10
# Location:      <project root>/frontend/css/styles-hero.css   (main script: <project root>/aiacolyte.py; subscripts: <project root>/subscripts/aiacolyte/)
# Description:   The hero of the AI Acolyte home page, the second of its three stylesheets (after
#                styles.css, before styles-sections.css): the wizard's workshop with the ambient
#                backdrop and star-dust, the heading with the two buttons beside it, the wizard, the
#                golden glows, the rune circle, the four holograms and the arcane terminal with its
#                spell colours, laid out for wide screens, tablets and phones. Uses the tokens and
#                keyframes of styles.css. Works with the main script, which serves it as
#                /static/css/styles-hero.css.
# Reads:         ../assets/img/ambient.webp; the tokens and keyframes of styles.css
# Writes:        nothing
# Sensitive:     none needed
# Arguments:     none (a stylesheet cannot take flags); aiacolyte.py --checkup confirms it is in place
# Changelog (last 15):
#   1.01  2026-09-10  First version: the hero part of styles.css 1.09, unchanged, moved here when styles.css was split (rule 9).
