Typing at a run boundary (e.g. near "Async" in a bullet) often lands the new text in a
browser-created wrapper element whose only child is that text. resolveStyleEl's sibling-only
search then found no data-fid run and fell back to dominantFid — which for a bullet is the bold
LABEL run (its first run) — so the inserted text rendered bold.
Make resolveStyleEl CLIMB toward the editor root and scan siblings at each level (nearest
preceding run first, then following), so it reaches the real run spans alongside the wrapper and
the inserted text continues the adjacent run's font. data-advances is still read only from the
exact wrapping span, so inherited fonts correctly re-measure. Text typed inside an existing run
is unaffected (step 1 returns its span immediately).

Reflow (primary editor):
- Geometric backstop in reflow_paragraph: adopt any text object fully inside the paragraph
bbox that the model's objectIndices omitted (PDFium glyph->object map can return -1), so it's
deleted + its original font is resolved. Fixes both the leftover-glyph "bulge/merge" and the
font-substitution-on-edit (same root cause). No-op on correctly-indexed paragraphs (gate-proven
byte-identical: overlay diff unchanged at 1.69%/1.70%).
- Preserve data-fid on edited contentEditable nodes (extractFlatRuns climbs to nearest styled
ancestor / inherits from adjacent run) so edits keep their real font instead of the dominant.
- Converge preview & commit through one buildReflowData (no preview-OK/commit-wrong drift).
- Center/right alignment: additive emission branch (greedy path only) + heading-align inference.
- IME composition handling (suppress render mid-composition; don't commit on composing Enter).
- Fix WASM document-handle leak (free superseded versions on documentId change/unmount).
- Quiet the backstop instrumentation (warn -> debug) now the root cause is confirmed.
Raw Text / StreamEditor (beta companion):
- Permission-gate both text_objects endpoints behind canModify; label tool "(beta)".
- P1a: preserve TJ kerning numbers for same-length edits (redistribute into original slots),
fall back to single-string collapse otherwise (never worse than before).
- P1b: reject edits with characters unencodable in the run's font (clear 400 instead of corruption).
- P2a: commit Raw Text edits as a new document version (add_document) and adopt the id via
pushHistory, so they join undo/redo instead of mutating in place.
- P2b: exact hit-boxes from real font metrics (re-measured once @font-face loads).
WASM preview rebuilt with the reflow changes; cache version bumped.
