Kegel pelvic floor trainer — Expo/RN MVP

Guided session timer: progressive squeeze-holds (5s +1s/3 sessions, cap
30s), reverse-kegel push holds, quick flicks in/out. Local-only progress
in AsyncStorage; signed APK via Gitea Actions on the desktop runner.

+# Kegel
+
+Pelvic floor trainer for sexual performance — a free, local-only take on what
+Stamina was before it went paid. Expo / React Native, Android + iOS.
+
+## How it works
+
+A session is four guided blocks driven by a step timer with haptic cues:
+
+1. **Holds** — 8 × squeeze-and-hold. This is the progressive-overload driver:
+   holds start at 5s and grow **+1s every 3 completed sessions** (capped at
+   30s). Manual ±1s adjustment in Settings.
+2. **Pushes** — 5 × reverse kegel (gently bear down). Scales at half the rate
+   of holds, capped at 12s.
+3. **Quick squeezes** — 10 × 1s burst contractions with 1s release.
+4. **Quick pushes** — 10 × 1s burst pushes with 1s release.
+
+Progress (session count, difficulty adjustment) lives in AsyncStorage — no
+server, no account.
+
+## Layout
+
+- `src/app/` — expo-router screens: `index` (home), `session` (timer), `settings`
+- `src/lib/workout.ts` — pure session-plan + progression logic
+- `src/lib/store.ts` — tiny local store persisted to AsyncStorage
+- `android/` — committed prebuild output; CI builds it directly
+
+## Development
+
+```sh
+npm install
+npm start            # Expo dev server
+npm run typecheck
+```
+
+## Release
+
+Push to `main` → Gitea Actions on the desktop runner (`runs-on: desktop`,
+never the VPS) builds a signed APK and publishes a Gitea release — install via
+Obtainium. Keystore: `~/.android-keys/kegel-release.jks` (repo secrets
+`KEYSTORE_B64`, `KEYSTORE_PASSWORD`; alias `kegel`). iOS runs via
+`npx expo run:ios` from a Mac.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
