- favicon is the Youreka logo (64px PNG generated from the source mark),
on the tools pages and server error pages
- signing out asks first: a Carbon cds-modal (Cancel / danger Sign out)
shared by the header and the mobile side nav; Cancel closes, Sign out
confirms and logs out
- the current tool is now visibly selected: Carbon marks active nav via
a[aria-current=page] INSIDE the shadow, but aria-current sits on the
host, so the rule never matched — the header item now gets a blue
underline and the side-nav link a blue left border (via ::part(link)
for colour, plus the host for the marker)
- logo and wordmark are middle-aligned inside a flex brand wrapper
- tests: favicon/modal/signout-trigger markup and the active-tool marking
on both navs (45 total)
