/**
 * Normalize-on-write helper (SPEC §11 "Резолюция").
 *
 * git diffs byte-for-byte, so writing a page in a NON-fixpoint markdown form
 * would make the next pull re-export it to a slightly different (but stable)
 * form and produce a phantom diff -> churny commits. The converter has a couple
 * of known one-pass asymmetries (a block image after a paragraph adds an empty
 * paragraph; a diagram materializes `data-align`), all of which converge to a
 * fixpoint after ONE `export -> import -> export` round-trip.
 *
 * So at write time we run exactly that one pass and persist the fixpoint form.
 * Already-stable content is unaffected (the pass is idempotent), so re-pulls of
 * unchanged pages produce identical bytes and git sees no diff.
