## Objective Fix missing characters in GPUI's web renderer for emoji-capable symbols that default to text presentation, such as repeated bare spider webs (`🕸🕸🕸`). The default Canvas policy previously rejected these symbols before checking whether bundled fonts could render them. ## Solution Separate emoji eligibility from presentation. Emoji-capable graphemes can now use Canvas when their glyph is missing, while existing bundled text glyphs remain native and explicit text/emoji presentation remains intact. CJK fallback remains opt-in. Add regression coverage for repeated spider webs and mixed bare, VS15, and VS16 sequences, including every glyph's source index and presentation, missing-glyph reports, copy preservation, and raster-cache reuse. ## Testing - `cargo test -p gpui_web --lib`: all 19 tests passed. - `cargo fmt -p gpui_web -- --check`, example Rust formatting, and `git diff --check`: passed. - `trunk build` in `crates/gpui_web/examples/hello_web`: passed. - Headless Chrome on macOS: browser regression failed against the old implementation and passed with the fix. Inspected the resulting screenshot; all mixed-presentation spider webs render. - Firefox, Safari, and other operating systems have not been exercised. To run the browser workflow, serve the gallery with `trunk serve` from `crates/gpui_web/examples/hello_web`, then run `node crates/gpui_web/examples/hello_web/test_canvas_fallback.mjs http://127.0.0.1:8080` from the repository root. Release Notes: - [GPUI] Fixed missing text-default emoji, including spider-web symbols, in GPUI's web renderer.
