# Script:        greatgallery.css    (stylesheet, loaded by frontend/pages/greatgallery.html)
# Created by:    Matthew Boucher
# Start date:    2026-10-13
# Location:      <project root>/frontend/css/greatgallery.css   (main script: <project root>/aiacolyte.py; subscripts: <project root>/subscripts/aiacolyte/)
# Description:   The look of The Great Gallery hub on top of styles.css and admin.css. It is deliberately plain and
#                matches the other pages: no images and no custom backdrop, just the site's standard admin
#                colouring and a grid of simple card links styled like the Forge/Server cards (the shared
#                gradient panel, a gold eyebrow label, a display-font title, a dim blurb and an ENTER cue, lifting
#                on hover). Works with the main script, which serves it as /static/css/greatgallery.css;
#                aiacolyte.py --checkup confirms it is in place.
# Reads:         the tokens and classes of styles.css and admin.css; ../assets/img/gg-patreon.webp (the Patreon plate)
# Writes:        nothing
# Sensitive:     none needed
# Arguments:     none (a stylesheet cannot take flags)
