Add hero/banner-overlay CSS variables and wire template.css
- Add HERO / BANNER OVERLAY section to light.standard.css and dark.standard.css:
--hero-height, --hero-color, --hero-bg-repeat, --hero-bg-attachment,
--hero-bg-position, --hero-bg-size, --hero-border-bottom,
--hero-overlay-bg (light: 0.1 alpha / dark: 0.3 alpha),
--hero-overlay-padding, --hero-overlay-text-align, --hero-overlay-text-color
- Replace all hardcoded values in .container-banner .banner-overlay and
.overlay with var() references (with fallbacks)
- Fix background-position: comma syntax → correct space-separated single-bg value
- Add css_vars_hero note field to CSS Variables tab in templateDetails.xml
- Add TPL_MOKOCASSIOPEIA_CSS_VARS_HERO_LABEL/DESC to en-US and en-GB
- Regenerate .min files
