+Done. Replaced the placeholder unicode glyphs in `NowPlayingScreen.kt` with real
+Material icons (`Icons.Filled.SkipPrevious/PlayArrow/Pause/SkipNext/VolumeUp`,
+plus `Repeat`/`Shuffle` leading icons on the chips) from
+`androidx.compose.material:material-icons-extended`.
 
-- Preferred source: **Google Material Symbols / Icons**. In Compose the usual
-  route is the `androidx.compose.material:material-icons-*` artifacts
-  (`Icons.Filled.PlayArrow`, `SkipNext`, `VolumeUp`, …). `material-icons-core`
-  covers the common set; `material-icons-extended` has everything but is large —
-  prefer core, or import only the specific vector assets we use.
-- Platform-bundled drawables (`android.R.drawable.ic_media_*`) exist but look
-  dated and vary by OEM — avoid; bundle our own for a consistent look.
-- Adding the dependency means a `deps.json` regen (see README).
+- That artifact bundles thousands of vectors, so the **debug** APK grew ~7 MB
+  (expected — debug can't shrink). Enabled **R8 + resource shrinking** on the
+  `release` build type, which strips the unused icons: release APK is ~1.2 MB.
+- Considered `material-icons-core` (too small — no media icons) and bundling
+  individual vector drawables (leaner but manual); the extended dep + R8 was the
+  best effort/quality trade.
