The top-nav account row carried min-height: 50px on top of the 8px
margin-top that Bootstrap base .navbar-form rule keeps at >=768px (the
override only zeroes the horizontal margins). The 8px was counted twice,
so the row ran from 8px to 58px: its icon tiles landed 8px below the 25px
midline that the 50px menu row and the logo define, and the navbar grew
from 50px to 58px, which also broke the body.nav-fixed offset.
Drop the min-height so the row takes its natural 34px height from the
icon tiles, and give the theme/language group the same 34px cross-size so
its 29px toggle shares that midline instead of sitting 2.5px above it.
Measured against the reference theme, the navbar goes from 66px to
50.05px (reference 50.28px) and the logo, menu, publish chip, VIP chip,
theme toggle and account icons all centre on 25px.
The desktop navbar stays visible below 991px (only the menu folds into a
dropdown there), so the same fix applies at the mobile and tablet
breakpoints: the top bar drops from 68px to 52.05px.
Verified: node --test across tests/ (603 passing), and a stubbed navbar
render measured in a headless browser against the reference theme
stylesheet.
