Subject: [PATCH] feat(mobile): sidebar nav becomes an app-grid on mobile (#7)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Below the desktop breakpoint (<1024px), the open/expanded sidebar's primary nav
renders as a 3-column grid of icon tiles with the title centered below each icon
(app-grid feel), instead of the desktop vertical list. Desktop and the collapsed
icon rail are unchanged.

- Scoped to `.sidebar-nav` so the footer "More" links are untouched.
- Token-only (no raw measurements), high specificity via the sidebar-expanded
  prefix (no !important). Labels wrap at spaces, not mid-word.
- Validated live in-browser; lint clean.

Option A (grid shows on the open mobile menu). An always-on variant was deferred —
it would require widening/overlaying the mobile sidebar.
