Defined in:
lib/arrolio/flowables/footnote_marker_flowable.rb

Overview

Zero-height placeholder that signals "the footnote with this id appears on the current page". The engine detects these during layout and records the footnote on the current Output::Page so the renderer can draw it at the bottom of the page.

Carries a reference to the full Content::Footnote (marker + body). The marker is also rendered inline (as a superscript indicator) by the flow builder when it constructs the run sequence; this flowable's sole job is to anchor the footnote to a page.
