Pure SX text layout library with one IO boundary (text-measure perform). Knuth-Plass optimal line breaking, Liang's hyphenation, position calculation. Library (lib/text-layout.sx): - break-lines: Knuth-Plass DP over word widths - break-lines-greedy: simple word-wrap for comparison - hyphenate-word: Liang's trie algorithm - position-line/position-lines: running x/y sums - measure-text: single perform (text-measure IO) Server font measurement (otfm): - Reads OpenType cmap + hmtx tables from .ttf files - DejaVu Serif/Sans bundled in shared/static/fonts/ - _cek_io_resolver hook: perform works inside aser/eval_expr - JIT VM suspension inline resolution for IO in compiled code ~font component (shared/sx/templates/font.sx): - Works like ~tw: emits @font-face CSS via cssx scope - Sets font-family on parent via spread - Deduplicates font declarations Infrastructure fixes: - stdin load command: per-expression error handling (was aborting on first error) - cek_run IO hook: _cek_io_resolver in sx_types.ml - JIT VmSuspended: inline IO resolution when resolver installed - ListRef handling in IO resolver (perform creates ListRef, not List) Demo page at /sx/(applications.(pretext)): - Hero: justified paragraph with otfm-measured proportional widths - Greedy vs Knuth-Plass side-by-side comparison - Badness scoring visualization - Hyphenation syllable decomposition 25 new tests (spec/tests/test-text-layout.sx), 3201/3201 passing.
