Pull request overview

Updates the Status Bar UX guideline to use the correct term discrete (not discreet) when describing background progress, keeping the guidance accurate and consistent.

Changes:

• Replace “discreet” with “discrete” in the background progress guidance text.
• Replace “discreet” with “discrete” in the accompanying example caption.

This sentence is hard to parse and is not in second person. Consider rewriting to a direct instruction (for example, start with "When you need to show..." and avoid "it's recommended").

Suggested change

	When needing to show discrete progress (progress happening in the background), it's recommended to show a Status Bar item with the loading icon (you can also add spin animation). If progress needs to be elevated for user attention, we recommend moving to a progress notification.
	When you need to show discrete progress, or progress that happens in the background, show a Status Bar item with the loading icon. You can also add a spin animation. If you need to elevate progress for user attention, move it to a progress notification.

[Copilot]

The caption uses "discrete", which many readers confuse with "discreet". Consider rephrasing the caption to avoid the ambiguous word (for example, describe it as "background" progress) since the section already defines the concept.
