The desktop target is the cheapest bug oracle you are not using
It builds in seconds, runs real Compose, and needs no device.

AnnotatedString is why you don't need three Text composables in a Row
Text takes a String or an AnnotatedString. The second lets one composable carry multiple styles, inline content and clickable spans — replacing the Row of Texts that breaks at large font scales.
A version catalog is a contract, and a transitive bump breaks it quietly
Declared versions are requests, not guarantees. Resolution picks the highest.
A shared ViewModel has no lifecycle, so you have to give it one
androidx.lifecycle.ViewModel is Android's. The shared class needs an explicit clear() and two platforms that call it.
A Flow is cold, and that is why your ViewModel fires three network calls
Each collector re-runs the producer. Two UI observers plus a test is three executions.
There is no Logcat in commonMain, and println is not a logger
Five targets, five sinks, and one of them discards your output silently.
Compose is growing a styles API, and it's for the gap theming never covered
MaterialTheme scopes values to a subtree, which is the wrong shape for reusable per-component configuration. Compose's styles direction addresses that gap; wrapper composables are the pattern to use today.
runTest skips your delays, which is why the flaky test passed
Virtual time makes a 30-second timeout instant — and makes a real-dispatcher leak invisible.
Source sets are a graph, and iosMain is not where you think it is
The default hierarchy creates intermediate source sets you never declared.
StateFlow drops what you needed and keeps what you didn't
Conflation turns two identical emissions into one, so a repeated event vanishes.
One failed child cancelled the whole screen, and the scope was the reason
Structured concurrency propagates failure upward by design. SupervisorJob is how you declare independence.
commonTest runs on every target, which is the point and the cost
One test, five executions. That is how you find platform bugs — and how one flaky test fails five jobs.
