• React Native + Expo
• Solana JSON-RPC (no SDK required)
• Expo Router (file-based navigation)

This app uses nested Expo Router navigators:

app/
|- _layout.tsx                (Root Stack)
|- (tabs)/
|  |- _layout.tsx             (Bottom Tabs)
|  |- index.tsx               (/)
|  `- swap.tsx                (/swap)
`- token/
   `- [mint].tsx              (/token/:mint)

How to think about this structure:

• app/_layout.tsx is the root Stack navigator.
• app/(tabs)/_layout.tsx is a child Tabs navigator mounted as the base screen in that stack.
• app/token/[mint].tsx is a stack detail route that pushes on top of tabs.

Why the tab bar disappears on token detail:

• Token detail is in the root stack, not inside the tabs group.
• Pushing /token/:mint covers the tabs layer.
• router.back() pops the stack and returns to the previous tab state.

Important route naming rules:

• _layout.tsx: navigator wrapper for sibling routes.
• index.tsx: default route for its folder.
• (tabs): route group for organization (not included in URL).
• [mint].tsx: dynamic segment captured from the URL.

Navigation methods used:

• router.push(...): add new screen to history.
• router.replace(...): replace current screen in history.
• router.back(): pop one screen.
• useLocalSearchParams(): read dynamic params like mint.
