The web file raises the app's 14px body size to that floor; the native file is the body size, so a phone renders exactly what it rendered before. maximum-scale=1 on the viewport meta was the other fix and was rejected: Android WebView honours it and it would take deliberate pinch zoom away from low-vision users."

So the page asks the shell for the device's own haptic instead, over the native.haptics.trigger notify behind the haptics grant: 70 to 77 bytes per frame, no reply, and haptics.ts's own Platform.OS split on the other side. A notify rather than a verb because nothing is owed back and a reply would spend a slot in the same in-flight window a forwarded request does, at 90 call sites (rulings-ota-c7.md ruling 30).

Both shells refuse window.open outright: iOS sets javaScriptCanOpenWindowsAutomatically = false and returns nil from WKUIDelegate's createWebViewWith, and Android sets javaScriptCanOpenWindowsAutomatically = false, setSupportMultipleWindows(false) and returns false from onCreateWindow.

This one asks the shell through the native.clipboard.write and native.clipboard.read verbs, where the pasteboard is the device's, and rejects when the route was not granted one so the caller's own catch puts that on screen. An image is the same pasteboard reached a different way: native.clipboard.read admits only text, and a 24 MiB base64 image cannot cross an 8 MiB reply cap, so readImage runs native.media.pick with source 'clipboard', reads the staged bytes back a chunk at a time and gives the handle back. contents answers per grant without probing, because the shell serves no 'is there text' verb and reading to find out would raise iOS's paste-consent prompt on every mount."

Retry and Remove are inert here: forceReconnect is null (client-context.web.tsx:45, read through host-client-hooks.ts:88) and removal refuses (page-host-removal-refusal.ts). The banner is reachable on the page because the shell forwards the native client's state (mobile-web-shell/bridge-host.ts:301) and auth-failed is in the wire enum (bridge/bridge-envelope.ts:44).

Both terminal fields reach their send through onSubmitEditing alone and both are bound here: the live input's carriage return, and the buffered command field's draft. The native file binds nothing, because that editor action needs no help; this one listens for beforeinput and acts on insertLineBreak and insertParagraph, the browser's own end-of-line signals. react-native-web calls preventDefault on every keydown it does submit on, so those events exist only in the cases it dropped and never produce a second carriage return; an IME still choosing a candidate reports insertCompositionText and is left alone."
