Quill

App icon: an elegant distraction-free writing app called Quill, literary and refined. Centered glyph: a fountain-pen nib with a center breather hole, rendered in #f8fafc. strictly flat, single solid background color, no gradients, solid background color #334155. Details: a subtly embossed glyph with a light top edge and shaded base. Requirements: square 1:1 canvas at 1024×1024, full-bleed background with no transparency, no text or wordmarks, no baked-in rounded corners or borders (the OS applies its own mask), glyph optically centered and contained within the central 66% safe zone so it survives the iOS squircle and Android circular launcher masks, crisp anti-aliased edges, high detail, professional app-store quality.
