react-native-svg materialises three native views per icon (SvgView + Group + Path). Feed screens render around a thousand icons, so that is ~2400 views and ~2400 shadow nodes of pure overhead per profile load. Move the 28 icons that repeat on feed screens - the post action bar, feed row reason, post embeds, the loading skeleton and the bottom tab bar - to react-native-nano-icons, which draws each icon as a single native text glyph. The SVG sources are generated from the existing icon path data so the geometry is unchanged, and `createNanoIcon` mirrors the `useCommonSVGProps` contract so call sites are one-line import swaps. Measured on a Samsung Galaxy A16 (SM-A165F, Android 16) with release builds, 10 runs per condition: native views -20.6%, icon construction -45.3%, JS-thread CPU -6.1%, main-thread CPU -3.3%.
