platform/linux/common

Shared Linux-safe code used by both the desktop simulator and the Pi OS device shell.

This layer is the neutral meeting point for:

  • tiny render primitives
  • simulator/device-agnostic app behavior
  • Linux-safe surface presentation contracts
  • Linux implementations of shared platform::ui::* runtime contracts such as settings, time, screen timeout, and generic device state
  • SQLite-backed Linux runtime state shared by simulator/device/uConsole shells
  • Linux map tile cache plumbing for online fetch plus local XYZ file cache
  • the shared Linux boot/menu shell session used by both the simulator and the thin framebuffer device shell

Code should move here only when it is genuinely shared between apps/linux_sim and apps/linux_rpi.
