• Studio (apps/studio)

Is your feature request related to a problem?

Yes. The dashboard overview header (OverviewHomeHeader.tsx) always greets the user with "Good morning, [Name]" regardless of the actual local time of day. This is a minor polish issue that hurts the premium feel of the app.

Describe the solution you'd like

The greeting should dynamically match the user's local time of day (e.g., "Good morning" from 5am to 12pm, "Good afternoon" from 12pm to 5pm, and "Good evening" from 5pm to 5am).

Describe alternatives you've considered

• A static greeting like "Welcome back, [Name]", which is less personalized.

Additional Context

Add a helper function/hook in OverviewHomeHeader.tsx to calculate the greeting based on the current hour:

const greeting = useMemo(() => {
  const hour = new Date().getHours();
  if (hour >= 5 && hour < 12) return "Good morning";
  if (hour >= 12 && hour < 17) return "Good afternoon";
  return "Good evening";
}, []);

Replace the hardcoded "Good morning" text with the dynamic greeting.
