Renderer provenance
This renderer follows the measured source-span layout and aligned overhead
annotations from Fluxtapose's reading-chapter-ui, including its later highlight
and underline work. The recovered source was the Nix-cached package at
/nix/store/2ka0jcdpyijmpjsrwqkap682l4xk88zi-source, rather than the earlier
prose-probe prototype. Fluxtapose's reading-app-2 references package revision
4e479c1a74c13d7467071da60b98fc148128dd99; exact cache revision is unconfirmed.

The original shared source/annotation flow is preserved: every annotation source has one row per physical text line. Long words and translations request horizontal padding around their source ranges and continue across subsequent lines. A forward capacity constraint replaces the ten-pass spacing loop; collisions never create additional annotation rows. Conflicting ranges from the same source share an ordered horizontal run. Row heights use all glyphs/ranges, and mixed font sizes share a baseline. Text keeps original UTF-16 offsets, including leading spaces and grapheme clusters. Measurement is injected for tests and uses a bounded cache in browsers. Canvas drawing and selection have no Konva or memoizee dependency.
Legal wrap positions use the pinned @cto.af/linebreak 4.0.3 implementation of
Unicode 17 UAX #14, intersected with Intl grapheme boundaries. Intl word
segmentation remains responsible for word targeting and preferred word affinity.
Source text and overhead labels use the same line-breaking layer. Closing marks
stay with preceding text, opening brackets stay with following text, and
annotation padding cannot insert a break inside those punctuation spans. Oversized
words and numbers use emergency tailoring of the alphabetic/numeric rules while
retaining punctuation rules; viewports narrower than an inseparable span still
require clipping. The package's Yarn lock and generated Nix dependency closure
retain the library and its transitive dependencies for reproducible browser builds.
