/**
 * Index marks (`:index[…]` and `:index{…}`, #165): the terms a back-of-book
 * index lists. The marks are taken out of the markdown before the block
 * parser runs — an invisible mark leaves nothing, a visible one leaves its
 * text — so they never change the spans, the line breaks or the layout;
 * the parse result's source offsets are mapped back to the original
 * markdown. Each mark keeps the source offset of the character it is
 * attached to (`anchor`): the build finds the page of the laid-out line
 * holding that character.
