flemming-it 6817752ae3 feat: studio.theme.solarized v0.1.0 builds against SDK

Promotes the skeleton to a real WASM plugin component. The
22 KiB stripped artefact at
target/wasm32-wasip2/release/studio_theme_solarized.wasm
is the proof-of-contract for fai-studio-plugin-sdk v0.1.

Implements:

- theme::Guest::theme_for(brightness) returning the
  pinned Solarized Light/Dark palettes (14 ARGB tokens
  each). Brightness names other than "light"/"dark"
  return PluginError::Declined.
- translate::Guest + output_view::Guest as Declined-only
  stubs — v0.1 of the SDK requires all three hooks per
  plugin; v0.2 will split the WIT.

Cargo.toml pins edition 2021 (matches SDK; wit-bindgen
0.36 codegen does not yet support edition 2024).

Raw Blame History

studio-theme-solarized

First in-tree Studio plugin. Ships Ethan Schoonover's Solarized palette as a Material 3 ColorScheme pair through the WIT theme export.

Status

v0.1 builds. The target/wasm32-wasip2/release/studio_theme_solarized.wasm artefact (~22 KiB stripped) is a valid F∆I Studio plugin component. What remains for full round-trip:

The Hub side needs an InvokePlugin gRPC RPC + a Component-Model loader path for studio-plugin-world components. Tracked as task #80.
Studio side needs plugin_host.dart + a theme-picker UI that lists installed studio.theme.* capabilities.

Until those land, this plugin can be inspected with wasm-tools component wit and packed via fai pack — /tmp/studio-theme-solarized-0.1.0.fai is sha256 e3d5aae44bb97f14f8f84e293ef8742700956b69c7d6fe46bb8b3c97fc1b23a0.

Palette

Ethan Schoonover's Solarized. 14 Material 3 tokens per brightness, in the order Studio expects (primary → on-primary → secondary → … → outline-variant). Both Light and Dark are explicit consts in src/lib.rs.

Why the source has three Guest impls

v0.1 of the SDK declares all three plugin hooks (theme, translate, output-view) in a single WIT world. A plugin that only cares about one hook still has to declare all three — the other two return PluginError::Declined, and Studio falls back to its built-in renderer / the [EN] badge.

v0.2 will split the WIT into one world per hook so a theme plugin only writes the theme impl. See docs/advanced/studio-plugin-sdk.md in fai/platform for the design notes.
