A centered, medium-width modal designed specifically for sign-in flows. It uses a clear vertical layout with a strong heading, supporting text, and stacked form fields. Primary actions are visually anchored at the bottom with a full-width button, while secondary auth options are separated by a subtle divider to reduce cognitive load. Includes an inline close control, generous spacing, and soft elevation to keep focus on the task without feeling heavy. Optimized for quick entry, scanning, and repeated use.
