- Added `6x12-dim`, `8x13-bw`, `8on16-bw`, `doc-8on16-bw`, `doc-8on16-sent`, and `doc-8on16-sent-dim` to `SHAPE_VARIANTS`, backed by new `Shape` fields `stretch`, `columns`, and `stopwordDim` and the X.org `6x12`/`8x13` fonts. - Added `dimStopwords()` (high-frequency function words printed in dim ink via zero-width markers, skipping already-dim spans) and `wrap()`, the greedy word-wrap used to typeset doc-layout pages; `geometry`/`render`/`renderMany`/`frames`/`compact` paginate doc shapes into `2 * rows`-line pages and persist `columns`/`stopwordDim` on compaction frames for mixed-shape detection. - Changed `normalize()` to keep line structure (whitespace runs containing a line break collapse to `NEWLINE_GLYPH`, U+2588 FULL BLOCK) and to drop unrenderable characters — ANSI escape sequences, control characters, zero-width format characters, combining marks, lone surrogates — instead of printing `?` blanks. - Explained the line-break marker in the frame-reading prompt `snapcompact-summary.md` and extended `snapcompact.test.ts` for the new variants, wrapping, and normalization. - Added the `research/parity_check.py` and `research/parity_render.ts` parity tooling for the native renderer. - Recorded the snapcompact changelog entries.
