# Script:        styles.css          (stylesheet, loaded by frontend/index.html, the login, password and System pages)
# Version:       1.10
# Created by:    Matthew Boucher
# Start date:    2026-09-10
# Location:      <project root>/frontend/css/styles.css   (main script: <project root>/aiacolyte.py; subscripts: <project root>/subscripts/aiacolyte/)
# Description:   The shared look of AI Acolyte, first of the home page's three stylesheets: the colour
#                tokens (palette pulled from the painting: candlelit umber, starry indigo, conjured gold
#                and a thread of arcane blue for the AI half of the magic), fonts, base elements,
#                buttons, the header with its clickable "A part of Mythical Layers 3D" line, the
#                keyframes and the reduced-motion rules. styles-hero.css (the wizard's workshop hero)
#                and styles-sections.css (spellbook, chalkboard, quote band, Oracle, contact scroll,
#                footer) load after it, in that order. The login, password and System pages use this
#                file with admin.css. Works with the main script, which serves it as /static/css/styles.css.
# Reads:         the font families defined in fonts.css
# Writes:        nothing
# Sensitive:     none needed
# Arguments:     none (a stylesheet cannot take flags); aiacolyte.py --checkup confirms it is in place
# Changelog (last 15):
#   1.10  2026-09-10  Split because it was over 1500 lines (rule 9): the hero moved to styles-hero.css, the page sections and footer to styles-sections.css; keyframes and reduced motion stay here for every page.
#   1.09  2026-09-10  Hero: the two buttons stand in a column to the right of the heading and intro (below them on phones); the terminal floats lower on wide screens so they never overlap; the menu stays on one line.
#   1.08  2026-09-10  Contact form rows: first/last name and email/phone side by side, one column when the form is narrow; "(optional)" note style.
#   1.07  2026-09-10  "A part of Mythical Layers 3D" is right-aligned with the end of the AI ACOLYTE name above it.
#   1.06  2026-09-10  "A part of Mythical Layers 3D" link: underline, arrow and brighter hover so it reads as clickable.
#   1.05  2026-09-10  Styles for the parent-site line under the header brand.
#   1.04  2026-09-10  Standard header and footer.
#   1.03  2026-09-10  Phone layout fixed (the one-column rule now follows the grid rules); hero scene centred on tablets.
#   1.02  2026-09-10  Deeper crystal ball, clean MAGIC glow on the chalkboard, contact eyebrow size, even form spacing.
#   1.01  2026-09-10  First version of the styles.
