- Active link no longer carries a background fill or pill. Instead, a
4px terracotta dot is centred 22px below the link via ::after. Quieter,
more confident, and survives the cream/white surface change without
needing a hover-area redesign.
- Vertical divider before the user's name shifts from the existing ghost-
border colour to a solid rgba(0,0,0,0.15) line, 18px tall with 18px
padding either side (replacing the prior --space-2 / 8px). Still a
scaled-1px element rather than a pipe character.
