Prevent Double-tap Zoom

MUST

MUST: `touch-action: manipulation` to prevent double-tap zoom; set `-webkit-tap-highlight-color` to match design

Set touch-action: manipulation on controls

Good

Why it matters

Mobile browsers delay click events by ~300ms to detect double-tap zoom. Setting touch-action: manipulation removes this delay for interactive elements, making the interface feel more responsive.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
