Rationale that explains a decision rather than the code below it belongs in the sandbox README or the PR, not in a header paragraph on every file.

/*
|
|
* What `yaakcli build --target sandbox` would need, beyond this:
|
|
*
|
|
* 1. `Platform::Browser` in the rolldown options (crates-cli/yaak-cli/src/
|
|
* commands/plugin.rs `bundler_options`), plus a resolver that fails on a
|
|
* Node built-in instead of shimming it — a silent shim turns a missing
|
|
* capability into a runtime error inside someone else's plugin.
|
|
* 2. A `runtime` field in the plugin manifest, so a plugin declares which
|
|
* target it is for and the registry can refuse to install a `node` plugin
|
|
* on a host that has no Node.
|
|
* 3. Both targets emitted for the same source where they both work, since a
|
|
* desktop with a sandbox and a desktop with Node are the same install.
|
|
* 4. Distribution as files, not as inlined strings. Inlining is what this
|
|
* script does because three small bundles cost less than an asset pipeline;
|
|
* the corpus does not, and a plugin the user installs at runtime cannot be
|
|
* inlined at build time at all.
