width: auto on a block element still fills the parent. Use width: max-content
so the button wraps its icon + label + padding only. Remove flex-grow: 1 on
the label span so it doesn't stretch within the now-natural-width button.

Google's gsi-material-button uses width: auto, not 100%. Replace width: 100%
/ max-width: 400px with width: auto + margin: 0 auto so the button sizes to
its content (icon + label + padding) and stays centered in the card.

Per Google's branding guidelines, the gsi-material-button requires Roboto
Medium. Add Google Fonts preconnect + stylesheet link to AuthLayout head.
Also add display:block + 100% dimensions to the SVG inside the icon
container to prevent inline baseline gaps.
