Section headings ("Beheer" / organisation name, "Platform") were
already uppercase + muted but read as bold paragraph dividers more
than as quiet group markers. Tighten letter-spacing, drop weight
from semibold to medium, lighten the color one step (surface-500 →
surface-400), and shrink text to 11px so the headings recede and
let the nav items themselves carry the visual weight.
Spacing nudged from mt-4/mb-2/px-2 → mt-6/mb-1/px-3: more breathing
room above each group, less below (the items already have py-2 on
top), and the heading left-edge now lines up with the icons of the
nav items beneath it (both at px-3).
