Top region A
ADV-PLACE-TOP-A. Two slideshows append to #presentation-region. This one is first in the field, so it should stay above Top region B.
Top region B
ADV-PLACE-TOP-B. appendTo, so this should appear after A. The page title is hidden when any paragraph sits in presentation_region.
Main Content Top A
ADV-PLACE-MAINTOP-A. prependTo #apb-main-content. The next special list also prepends, so B should end up above A.
Main Content Top B
ADV-PLACE-MAINTOP-B. Second prepend. Expected visual order: B, then A, then Body content.
Placement gauntlet
Placement is one pass on setTimeout(0). A locator that is not in the DOM yet is a miss, and the paragraph stays hidden (data-apb-placement-pending). Region items below emit #internal-placement-1 and #internal-placement-3 before any parent targets them. Internal Placement 2 is targeted before its region exists, on purpose.
Sidebar Top and Bottom target IDs that this theme only prints inside sidebar_first. There is no block there, so those two bands should never appear.
Early region anchors (1 and 3)
ADV-PLACE-REGIONS-EARLY. Active region items whose titles are exactly internal-placement-1 and internal-placement-3. Field order puts this parent before the accordion and tabs that target those locators.
Moved into Internal Placement 1
ADV-PLACE-INT1. If you can read this, a simple-content region item is enough to make Internal Placement 1 work. Capabilities documented the miss because no page had emitted the ID yet.
Targets Internal Placement 2 too early
ADV-PLACE-INT2-EARLY. The region for #internal-placement-2 is later in the field. One-pass placement should leave this pending.
Late region anchor (2) and a dead one
ADV-PLACE-REGIONS-LATE. internal-placement-2 arrives after its consumer. The inactive region titled adv-custom-drop emits no ID (Active Region is off). Custom IDs also cannot be targeted: the vocabulary is a closed list of ten locators.
Moved into Internal Placement 3
ADV-PLACE-INT3. Region 3 was emitted early. Tabs JS must still attach after the move.
Internal locators use prependTo. An empty drop zone behaves like append. Two consumers would reverse.
No container
ADV-PLACE-NOCONTAINER. Main Content - No container. Placement wraps the section title in .section-title-inner. WOW fade-in is applied to #main-content-no-container > .paragraph, unlike other drop zones.
Main Content Bottom
ADV-PLACE-BOTTOM. appendTo #apb-main-content. Should be after Body bands, including the late region parent.
Second paragraph.
Sidebar Top (expected hidden)
ADV-PLACE-SIDE-TOP. If this is visible, sidebar_first gained a block and #sidebar-top exists.
Sidebar Bottom (expected hidden)
Same miss as Sidebar Top. #sidebar-bottom is inside the same Twig if.
