Fix the three remaining sub-16px inputs, then drop user-scalable=no / maximum-scale=1 from the viewport meta (a11y)

[tiero]

From the mobile-feel audit. The main input stack is already zoom-safe (.input is 1rem, swap search fields are explicit 16px, and tokens.css:151-152 even documents the 16px-inputs intent). But the app still ships maximum-scale=1.0, user-scalable=no (index.html:7-8) as a crutch, and that has two costs:

• Accessibility: Android Chrome honors both directives, so pinch-zoom is genuinely blocked for low-vision users (WCAG 1.4.4).
• It doesn't even cover everything: iOS Chrome/Firefox and several embedded WKWebViews ignore maximum-scale, so the sub-16px inputs below already auto-zoom there today.

The three live sub-16px controls

1. InputNsec bare input — src/components/InputNsec.tsx:15 renders a raw <input> with no class and no font-size (live via Init/Restore.tsx:153). No CSS rule sizes bare inputs, so it falls to the sub-16px browser default. Fix: give it the shared .input class like every other Input* component.
2. Contracts search input (devMode-gated) — src/screens/Settings/Contracts.tsx:344 hardcodes fontSize: 14 inline. Fix: 16 / .input.
3. Solvers JSON editor textarea — src/screens/Settings/Solvers.tsx:96 hardcodes fontSize: '14px' (applied to the textarea at line 105; the screen is live and ungated). Fix: '16px' — monospace at 16px is still compact, rows={21} unaffected.

Then relax the viewport meta

<meta name="viewport" content="width=device-width, initial-scale=1.0, viewport-fit=cover" />

Double-tap zoom stays suppressed by body { touch-action: manipulation } (src/index.css:132); the only behavior change is restoring pinch-zoom on Android — an accessibility win.

Latent (dead-code) offenders, fix-on-adoption

The unused shadcn primitives ship sub-16px on focusable elements: ui/native-select.tsx:20 (text-sm on a native <select> — iOS zooms on select focus too), ui/command.tsx:58-61 (text-sm on the real cmdk input), and md:text-sm drops ui/input.tsx:12 / ui/textarea.tsx:10 to 14px on iPad-width viewports (iPad Safari also auto-zooms). Change to text-base on the focusable elements if these are ever adopted.
