Text Field

Plain `<input>` with no state, so it stays a server-compatible component (no
`"use client"`). Invalid styling keys off the `aria-invalid` attribute
(`aria-invalid:` variant), so the accessible state and the visual state can't
drift. File styling uses Tailwind's `file:` variant on the
`::file-selector-button` pseudo-element. Renamed from shadcn's `Input` to
`TextField`; the slot is `text-field`.

**Pebble (2026-11-03).** Field is a recessed well: `bg-card`, full-strength `border-control`, `inset-shadow-xs`; hover darkens the edge; focus uses the 2 px ring with offset; disabled fills `bg-muted`. Added optional `leading`, `trailing`, `valid` and `rootClassName`. Without them the component is still a bare `<input>`, so existing layouts are untouched; with them a `group/field` wrapper positions 36 px adornment columns and pads the input. The leading icon turns foreground on `focus-within`. `valid` adds a success-filled tick that pops in via `@starting-style` (`starting:scale-50 starting:opacity-0`), so no client JS is needed and the file stays a server component; reduced motion drops the transition. The wrapper is chosen by value: a set adornment, `valid`, or a string `rootClassName`. An earlier version chose it by key presence (`key in props`), which wrapped every field rendered through a component that forwards the props (even as `undefined`) and silently moved `className` off the layout item; value-based keeps such wrappers bare. Fields whose adornments toggle pass `rootClassName` (even `""`) as the explicit opt-in, so the wrapper stays mounted and the input keeps its focus and uncontrolled value.
