iOS auto-zooms on input focus in web UI

[xpcmdshell]

Description

When accessing opencode web from iOS, tapping the "Ask anything..." input causes the page to auto-zoom. iOS WebKit (used by all iOS browsers) zooms on any input with font-size < 16px as an accessibility feature. This cannot be disabled except by increasing the input field size.

Affected elements:

• Prompt input (contenteditable div with text-14-regular = 14px)
• TextField component (font-size: 14px in text-field.css) Partial Fix: Add to packages/ui/src/styles/base.css:

@media (hover: none) and (pointer: coarse) {
  input,
  select,
  textarea,
  [contenteditable="true"] {
    font-size: 16px !important;
  }
}
