## Fix
- [ ] **Colours are not in a defined colour space. Fix this before a
styling pass.** Both render backends prefer an sRGB surface
(`default/render.rs` and `android/render.rs`), while `fs_main` returns
`unpack4x8unorm` palette and image bytes unchanged. An sRGB attachment
treats those values as linear and encodes them again: Mocha Crust
(17,17,27) became (73,73,91) in a desktop screenshot measured on
2026-09-06.
Neither diagnostics nor startup logging records Android's selected surface
format. A device exposing only a non-sRGB surface can hide the shared bug.
Done means defining one convention for palette bytes, decoded images,
colour emoji and the clear colour, then converting exactly once for the
selected target. Record the selected format in diagnostics, and add a GPU
test that draws known non-black, non-white pixels into an sRGB target and
reads the stored bytes back; screenshots from desktop and Android then
confirm the same Catppuccin values rather than serving as the definition.
## Build (for the port)
Framework capabilities needed by `RUST.md`'s port plan:
- [ ] **Selectable, read-only text.** P0's report and P1's transcript rows
use `TextEdit` because `Selectable` is implemented only for it. That
makes prose focusable and opens the IME over text that cannot be edited.
A display widget needs the same selection geometry and clipboard path
without a text-input accessibility role or keyboard focus.
- [ ] **Overflow ellipsis with an explicit retained end.** `TextAttrs` can
only wrap or clip, so a tool summary is cut with no mark. Parley has no

Standalone images currently use `NonFiltering` sampling. Thumbnail scaling
and filtering remain image-widget decisions, not texture-storage decisions.
## Colour convention
Palette literals and decoded image bytes enter Iris as straight-alpha sRGB.
Solid paints are converted once when registered and stored in a separate GPU
paint table as linear `vec4<f32>`; rect and glyph primitives carry only the
paint-table index. `Paints::set` rewrites a slot in place, so a shared theme
can change without rebuilding widgets or primitive buffers. A rect may also
hold a `Paint` definition and resolve it to a `PaintId` on its first draw;
independently constructed definitions deliberately receive independent slots.
Standalone images, colour glyphs, and atlas pages use
`Rgba8UnormSrgb`, which makes sampling decode their RGB channels to linear
light. Shaders therefore always return linear values. Both window backends
render through an sRGB texture view in `SurfaceColorSpace::Srgb`, which
encodes exactly once on output; the clear colour is linear too. A surface
without an advertised RGBA/BGRA sRGB view and sRGB output space is rejected
rather than silently displaying a different colour pipeline. The readback
test in `iris/tests/color_space.rs` guards the solid, image, and in-place
theme-update paths end to end.
