A TextBuffer used to have exactly one style for its whole string, applied via parley's push_default. SpanStyle adds a second, optional layer -- a byte range plus whichever of colour/family/font size/ bold/italic/underline it overrides, pushed with parley's own push(property, range) -- so a heading, bold, inline code and a link can each carry their own look inside one wrapped, selectable TextEdit. This is the actual answer to RUST.md's E2 finding against Masonry (TextArea::edit_styles() is one StyleSet for the whole editor). PlacedGlyph gains a color field, read from parley's own per-run Style::brush, and Painter::glyphs draws each glyph in its own colour instead of one colour for the whole RenderedText. Real bug found while wiring this into a live screen (not caught by any test, since markdown's own tests only check string/range logic): spans were threaded through TextOutput::run but not the sibling TextEditOutput::run, so every editable field silently dropped them. Fixed in build.rs; see IRIS.md's entry for why both call sites are a pair to keep in sync. cargo fmt/build/clippy/test --workspace and cargo ndk (iris, iris-android excluded per its own workspace exclusion) all clean; 28 existing iris tests unaffected.
