Fix styling of button-like links on page banners.
Review Request #14611 — Created Sept. 12, 2025 and submitted — Latest diff uploaded
Page banners were setting some styles for links, but applying these to
buttons as well. Links with a button-like appearance should continue to
look like buttons. The CSS for the page banner is now careful to only
apply these styles to non-button links.
Tested with a page banner with link-based buttons.
