Kids Mode v1.1.0

Kids Mode now looks and feels like part of Onion OS — every screen renders
through Onion's own theme engine — plus smarter timer controls and a
PIN system that can't lock you out.

Highlights

• Native Onion look: your active theme's background, fonts, and colors
  everywhere — header bar with battery, footer button hints, and an
  Apps-menu-style parent menu with full-width rows
• Add play time inline: on the parent menu row, ◀ ▶ picks +5…+50 min
  and A applies — with a live preview of what the remaining time becomes
• Turn off timer: new parent-menu option that removes any running timer
  entirely for unlimited play (until re-armed or time is added again)
• Auto power-off: if the "Time's up!" screen is left alone for 5 minutes,
  the device shuts down cleanly instead of draining the battery overnight
• PIN improvements: A confirms (up/down changes a digit, left/right
  moves); a wrong PIN lets you retry on the same screen; and the PIN now
  survives app updates via a snapshot in Saves/kidmode/ — if no PIN exists
  at all, the unlock gesture asks you to set a new one instead of locking
  you out

Install

1. Download KidsMode.zip below
2. Copy the KidsMode folder into App/ on your SD card (so it becomes
   /App/KidsMode/)
3. Reboot, then arm from Apps → Kids Mode

Updating from v1.0.0: replacing the KidsMode folder resets the PIN
once (the update-proof snapshot didn't exist yet). If the device was armed,
hold SELECT+START and you'll be asked to set a new PIN. From v1.1.0
onward, the PIN survives updates.

Requires Onion OS 4.3+. Tested on a Miyoo Mini Plus running Onion
4.4-beta; base Mini and Mini V4 are supported in code but less tested —
reports welcome.
