Theme Name: ATB Lite
Theme URI: https://gc-airporttransfers.com.au/
Author: Gold Coast Airport Transfers
Author URI: https://gc-airporttransfers.com.au/
Description: The companion theme to the Airport Transfer Booking plugin. Lightweight, citation-first markup: semantic landmarks, one H1 per page, breadcrumbs and silo links, an engine-built answer block at the top of every route page, no jQuery, no block-library, a single tiny nav script. Applies no styling of its own to the booking form, so the form always renders exactly as the plugin intends.
Version: 1.2.3
