"""Icons: hand-painted panel-collapse toggles + a shared line-icon library
rendered from local SVG path data — no external image files, no network fetch,
so every icon stays crisp at any size and recolors for the light/dark theme.

The glyph set is ported 1:1 from the Nova Platform web app's shared icon
library (``nova-platform/apps/web/components/ui/icons.tsx``) so the desktop app
and the web platform show the SAME icons. Same Feather-style thin stroke, same
``viewBox 0 0 24 24``, same ``stroke-width`` (1.7) — the only difference is the
render path (Qt ``QSvgRenderer`` here vs. React ``<svg>`` there).

Entries fall into three groups below: (1) the full Nova set under Nova's own
names; (2) a few app-specific glyphs Nova doesn't define (save/new/attach/…),
drawn in the same thin-stroke style; (3) legacy aliases so this app's existing
``icon("chat"/"document"/"flask"/"sparkle"/"settings")`` call sites keep working
— each alias points at the matching Nova design (message/file/beaker/sparkles/
gear). Feather Icons and the derived Nova set are MIT-licensed."""
