Breadcrumbs text and default links fail contrast ratio
https://v5.getbootstrap.com/docs/5.0/components/breadcrumb/
The active text/separator for breadcrumbs uses #6c757d
on #e9ecef
with a contrast ratio of 4:1. The default links in breadcrumbs use #0d6efd
on #e9ecef
with a contrast ratio of 3.8:1.
bumping the text/separator from $gray-600
to $gray-700
(#495057
) shoots up the contrat to 6.9:1. For the links, however, there's very little wiggle room ... not sure how/if that can be tackled - #0d6efd
has a ratio of 4.5:1 only against pure white, so even lightening the breadcrumbs background a bit won't help
