I just checked the video. Perhaps we should hide the animated border for items in case of errors?

Overall nice improvement! 🔥

Walkthrough

This change introduces error banner support for the web import feature in the IDE plugin. A new BannerAction data class and actions property enable banners to display clickable actions. New event types track icon download and font load failures, mapped to a WebFailureReason enum for localization. Error banner integration in StandardImportScreenUI and SvgImportScreenUI displays failure messages with localized text and, for font failures, a retry action. Logging is added to view models for diagnostic purposes. A changelog entry and six new localization keys document the feature.

In
`@tools/idea-plugin/src/main/kotlin/io/github/composegears/valkyrie/ui/screen/webimport/common/StandardImportScreenUI.kt`:
- Around line 95-97: The handler for StandardIconEvent.IconDownloadFailed is
clearing selectedIcon unconditionally, allowing stale failures to clear a newer
selection; update the event type to include the icon identity (e.g., add an id
or URL field to IconDownloadFailed) and then, inside the
StandardIconEvent.IconDownloadFailed branch, compare the event's icon identity
against the current selectedIcon before setting selectedIcon = null and showing
the banner; alternatively, change the download flow to use a coroutine operator
like collectLatest/flatMapLatest so only the latest download result is delivered
(adjust code around downloadJob?.cancel(), the download coroutine, and the
StandardIconEvent handling to match the chosen approach).
