The active ayah should be clear, not loud
Ayah Flow is the interface idea behind the project: previous ayahs appear softly above, the active ayah is brighter in the middle, and the upcoming ayah waits below in a dim state.
This makes the visual language understandable at a glance. A viewer can immediately see that the display updates as the imam continues reciting.
Less information may be better
A salah-oriented interface should not behave like a phone. It should avoid notifications, animations and overloaded text. The goal is meaning, not distraction.
A good prototype should test font size, brightness, timing, field-of-view placement and whether the user can keep attention in prayer.
