Dim sum surprise
A small, un-opt-outable 10% chance at each startup of showing a randomly chosen dim sum dish's name and picture.
Behavior
On roughly one in ten launches, a bundled local image of a dim sum dish is meant to appear briefly with its name in both English and Chinese, then dismiss itself automatically without blocking the interface from becoming usable.
Configuration
There is deliberately no setting to turn this off; the only configurable aspect is that School mode, once it exists, would suppress it along with every other optional capability.
Current status
Desktop application: Partial. dim-sum-surprise.ts implements the whole draw as specified and as tested: a one-in-ten chance per launch with an exclusive probability boundary, exactly one draw per launch, suppression during a first run, an error path, an update, a mid-task flow and quiet hours, bilingual dish names with alt text, bundled local images, and a deliberate absence of an off switch (storedPreferenceIsIgnored() asserts that as a checkable fact). None of it runs: nothing in the mounted application calls this module. A grep for its two exports (surpriseFor, storedPreferenceIsIgnored) across App.tsx, main.tsx, PbxAdminApp.tsx and PbxAdminIntegratedApp.tsx finds no reference outside the module and its own test. Every real launch of the built application currently has a zero, not a one-in-ten, chance of showing a dish.
Documentation website: Not implemented. A static documentation site has no startup event to attach this to.
Failure modes
If the bundled image set were ever missing an entry, the intended behavior is to skip that draw rather than show a broken image; the desktop module implements this, but since nothing calls the module, the behavior has never run outside its own test.
Accessibility and localization
This feature is expected to follow the product's standing accessibility contract: keyboard reachability, visible focus, correct roles and names, and respect for a reduced-motion preference. The module's tests cover alt text for screen-reader users, but the surface itself is never mounted, so there is nothing in the running application to check focus order or motion behavior against yet.
Verification
tests/ui/dim-sum-surprise.test.tsx exercises the draw logic, suppression rules, and the no-off-switch guarantee directly, in isolation from the running application. Verifying the wiring gap means launching the built desktop application repeatedly and confirming no dish ever appears -- which is the current, correct result, and the defect this article records.
