Available how-tos

• Style a component — StyleSheet.create vs a Vue SFC <style> block.
• Handle press/change events — React callback props, Vue emits, Angular @Output().
• Two-way bind a value — Vue v-model, Angular [(value)].
• Share content across surfaces — createPortal/Teleport vs createTunnel.
• Write platform-specific code — the X.ios.ts/X.android.ts/X/shared.ts folder convention.
• Wrap a third-party native view — why the library’s React component can’t be reused, and what can.
• Turn on diagnostic logging — dlog/isDebug and the DEBUG env var.
