-             * Create mpv config directory and copy font files to ensure SubRip subtitles load properly on Android.
-             *
-             * Technical Background:
-             * ====================
-             * On Android, mpv requires access to a font file to render text-based subtitles, particularly SubRip (.srt)
-             * format subtitles. Without an available font in the config directory, mpv will fail to display subtitles
-             * even when subtitle tracks are properly detected and loaded.
-             *
-             * Why This Is Necessary:
-             * =====================
-             * 1. Android's font system is isolated from native libraries like mpv. While Android has system fonts,
-             *    mpv cannot access them directly due to sandboxing and library isolation.
-             *
-             * 2. SubRip subtitles require a font to render text overlay on video. When no font is available in the
-             *    configured directory, mpv either:
-             *    - Fails silently (subtitles don't appear)
-             *    - Falls back to a default font that may not support the required character set
-             *    - Crashes or produces rendering errors
-             *
-             * 3. By placing a font file (font.ttf) in mpv's config directory and setting that directory via
-             *    MPVLib.setOptionString("config-dir", ...), we ensure mpv has a known, accessible font source.
-             *
-             * Reference:
-             * =========
-             * This workaround is documented in the mpv-android project:
-             * https://github.com/mpv-android/mpv-android/issues/96
-             *
-             * The issue discusses that without a font in the config directory, SubRip subtitles fail to load
-             * properly on Android, and the solution is to copy a font file to a known location that mpv can access.

- * Wrapper around the dev.jdtech.mpv.MPVLib class.
- * This provides a consistent interface for the rest of the app.
+ * Per-instance wrapper around the dev.jdtech.mpv.MPVLib class.
+ *
+ * libmpv 1.0 exposes an instance-based API: each `LibMPV.create(ctx)` returns
+ * a fresh, independent handle. Each player creates its own MPVLib instance
+ * (Findroid pattern) and on teardown we simply drop the reference. We do NOT
+ * call `LibMPV.destroy()` — its native implementation has an internal
+ * use-after-free on libmpv 1.0 that we cannot fix from Kotlin. Letting the
+ * GC reach the JVM-level finalizer (or never reaching it, since the native
+ * handle lives in process-global state until exit) is strictly safer than
+ * crashing.
+ *
+ * Trade-off: mpv's native footprint (decoder + demuxer cache) for one player
+ * stays allocated until the next player's allocation displaces it in scudo's
+ * arena. On a TV app where the player is the dominant memory consumer and
+ * only one player is alive at a time, this is acceptable.
