"""Mobile (Feishu H5) backend module.

Mobile-specific API surface that bundles first-screen data so the
``/m/*`` H5 client only needs one round-trip per page, instead of the
5-6 parallel requests the original mobile home page used to fan out.
Feishu in-app webview on iOS has noticeable per-request latency under
mobile networks, so collapsing the fan-out is the primary lever for
perceived first-paint speed.

Lives under ``server/app/mobile/`` rather than being scattered across
domain modules because the aggregation crosses domain boundaries
(asset + provisioning + notifications + offboarding + ...) and the
mobile UX surface is a long-term cohort, not a per-feature add-on.

Endpoints (mounted at ``/api/v1/m``):
  - ``GET /m/aggregate/home``  — role-aware first-screen payload
  - ``GET /m/apps/catalog``    — navigable app grid + default pins

Subsequent mobile milestones extend this module with KPI aggregates
(``/m/aggregate/kpi/...``) and per-page payloads that need similar
fan-in collapsing.
