Podlite 1.11: install internally, keep loaded roots

Installed on the SD card, the app was killed whenever the card was shared over USB,
and a failed root read left HTTPS broken until a restart.

 # Podlite
 
-A tiny Audiobookshelf **podcast** client for the Samsung Galaxy Mini (GT-S5570) and other Android 2.2+ phones. Native Java, no libraries, ~130 KB. The interface is in Galician, with large text and touch targets sized for the Mini's 240×320 screen. Its purple colour scheme and launcher icon come from the Audiobookshelf icon pack (`art/icon_master_512.png`); `tools/make_icons.py` derives the notification and player icons from it.
+A tiny Audiobookshelf **podcast** client for the Samsung Galaxy Mini (GT-S5570) and other Android 2.2+ phones. Native Java; the APK is about 1.1 MB, nearly all of it the bundled TLS stack. Formerly MiniABS. The interface is in Galician, with large text and touch targets sized for the Mini's 240×320 screen. The launcher icon is the "Podcasts Radio" pack (master in `art/icon-master.png`); `tools/make_icons.py` draws the notification icon (a white radio silhouette) and the player icons. Its warm dark colours and amber accent come from the radio: brass and the glow of its dial.
 
 ## Install
 
 1. Copy `Podlite.apk` to the phone (USB to the SD card, or download it in the browser).
 2. On the phone: **Settings → Applications → Unknown sources** → tick it.
-3. Open the APK from a file manager and install. It can be moved to the SD card (Settings → Applications → Manage applications → Podlite → Move to SD card).
+3. Open the APK from a file manager and install. Podlite installs to internal storage (about 1 MB): an app on the SD card is killed whenever the phone shares its SD card over USB, which stopped playback and broke HTTPS until a restart.
