closes #14430

Summary by CodeRabbit

• Documentation
  • Expanded the WebAssembly lazy-loading guidance, including route-based loading, loading custom implementations, and requirements for different Blazor hosting and render modes.
  • Clarified that Bink-dependent types must not be used by assemblies read at startup, and that lazy-loaded implementations must be placed in an assembly loaded with Bink.
  • Added AOT-specific configuration guidance and troubleshooting information for assembly-loading failures.
  • Updated the quick-start and setup guides to describe when Bink can be loaded on demand.

Walkthrough

The documentation now describes lazy loading Bit.Bink on WebAssembly. It adds route-based loading guidance, hosting-model setup details, AOT constraints, and troubleshooting references.

Changes

WebAssembly lazy-loading guidance

Layer / File(s)	Summary
Main guide and setup instructions src/Utilities/Bink/README.md, src/Utilities/Bink/Bit.Bink/README.md	The guides describe route-based loading, constraints on references to Bink types, custom implementation placement, hosting-model setup, and AOT behavior.
Demo guidance and troubleshooting src/Utilities/Bink/Demo/Client/..., src/Utilities/Bink/Demo/Server/...	The demo links to the lazy-loading guidance, updates setup instructions for hosting models, adds search keywords, and includes an assembly-loading symptom and prompt guidance.

Merge Risk: Low · previous review 239cb

The guidance is mergeable with minor corrections or follow-up: match the whiteboard route segment and clarify that applications must include every drawing route in their loading check.

Full details: Linked Issues check

Explanation

Issue #14430 is open and directly linked, but it gives no acceptance criteria or specific coding requirement. The PR adds focused lazy-loading guidance for Bink in the package README and demo documentation. It covers assembly marking, router loading, render modes, custom types, registration timing, and AOT constraints. The demo search and diagnostic guidance also reference the new section.

Full details: Out of Scope Changes check

Explanation

The changed files support the lazy-loading topic in #14430. README updates document the feature. Demo guide, search keywords, MCP prompt text, and completion text expose or diagnose the same feature. No unrelated product behavior or unrelated documentation change is shown by the reviewed diff.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 4 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

_{A rabbit reads the loading guide,
Then hops where canvas pages hide.
It waits until the route is near,
And loads the needed code with cheer.
AOT stays clear of lazy flight,
The bunny nibbles docs tonight.}

Inline comments:
Review comments at @src/Utilities/Bink/Demo/Client/Pages/GettingStarted.razor:
- Around line 240-241: Update the lazy-load sample’s comment near the
context.Path.StartsWith("whiteboard", StringComparison.OrdinalIgnoreCase) check
to clarify that it covers only /whiteboard and that other drawing routes must be
added, or extend the route check to include every drawing page, including
/signature.

Review comments at @src/Utilities/Bink/README.md:
- Around line 1732-1733: Update the whiteboard route check in the `context.Path`
example so it matches only the exact `whiteboard` path or paths beneath the
`whiteboard/` segment; do not match unrelated prefixes such as
`whiteboard-settings`. Keep the `Bit.Bink.wasm` load for matching drawing
routes.
