The per-section icon colours used :nth-child(1..6), but the nav grew to 8
items (files, shared, shared-with-me, recent, favorites, photos, music,
trash). The colours had drifted out of sync with their labels, and music
and trash got no colour at all.
Map each item's colour off a stable `data-section` key instead, covering
all eight sections with distinct curated calendar-dot hues (sibling blues
for the two share directions, purple for music, red for trash). Reordering
or adding nav items can no longer desync the colours.

Two related parity gaps from the VanillaJS → Svelte migration (issue #500):
internal-vs-external users weren't badged, and external users in a share's
member list rendered as a bare UUID with a static icon — no avatar, no email.
Both share one root cause: there was no shared user vignette and no resolver
for non-directory (external) users (the system address book lists internal
users only, and ShareDialog hardcoded isExternal=false).
- lib/api/endpoints/users.ts: resolveUser(id) — cached GET /api/users/{id}
(the authenticated per-user profile lookup) → {name, email, image,
isExternal}; returns null when the profile isn't visible so callers keep
their fallback label.
- lib/components/UserVignette.svelte: reusable identity chip — avatar (photo
or coloured initials), name, email, and a building-circle-xmark badge for
external users; resolves lazily and falls back to a caller-supplied label.
- lib/utils/avatar.ts: userInitials() + avatarColorIndex() extracted from
AppShell (now shared by both — no duplicated logic) so vignette and account
button render identically.
- ShareDialog: user member rows now render <UserVignette>; groups keep their
icon+label. Drops the dead hardcoded isExternal.
Backend already exposes everything (UserDto.email/image/is_external via
GET /api/users/{id}); no backend change. Frontend gate green (svelte-check
0/0, eslint, stylelint, prettier) + 47 Vitest.
