Subject: [PATCH 01/12] feat: add ControlPresentation primitive
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A presentational layout shell for input-like controls. Provides border
chrome, focus/hover/disabled/readonly/invalid styling, and two slots
(startSlot, endSlot) flanking an arbitrary focusable control passed as
children. Forwards a ref to the wrapper and forwards click events to the
inner control (toggleable via forwardClickToControl).

State-driven styling fires from :has() selectors that match three
signaling conventions — native HTML, ARIA, and data-attr — on the inner
control. The single source of truth is the a11y attributes the control
needs anyway. :invalid is deliberately omitted (fires pre-interaction).

Spacing is explicit conditional padding: 10px outer on each side by
default; left shrinks to 6px when startSlot is present (with 6px gap to
control); right shrinks to 4px when endSlot is present (with 6px gap).

ControlActionButton ships alongside as a compact 24x24 button variant
sized to fit the chrome alongside a 16px icon glyph.

Subject: [PATCH 02/12] test: add coverage for ControlPresentation

Cover the public API surface (slot rendering, click-forwarding, ref
forwarding, attribute passthrough, exceptionallySetClassName) plus each
state-styling signaling convention (native HTML, ARIA, data-attr) and
the slot-marker classes that drive the conditional outer padding.
jest-axe smoke test for accessibility.

Subject: [PATCH 04/12] refactor: use flex gap instead of slot margins for slot
 spacing

Replace margin-inline-{end,start} on .startSlot / .endSlot with a single
gap: 6px declaration on the .container flex wrapper. The rendered
geometry is identical (flex gap only applies between rendered children,
so absent slots still produce no gap), but the spacing rule lives in one
place and can't drift between the two sides.

Subject: [PATCH 05/12] fix: prevent onClick from firing twice on wrapper
 background click

When the wrapper background is clicked, handleWrapperClick synthesizes
control.click() to activate the inner control. That synthetic click
bubbles back up to the wrapper and re-enters the same handler, which
called onClick a second time. Track the dispatched re-entry via a ref
and short-circuit it so consumer onClick fires exactly once per user
gesture.

Subject: [PATCH 06/12] refactor: prune ControlPresentation test suite to
 behavioral coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

30 → 12 tests. The pruned tests were either (a) asserting React's own
attribute-passthrough behavior (the entire state-styling describe block —
JSDOM doesn't evaluate the :has() CSS that gives those attributes
visual meaning), (b) locking in implementation details (role attributes,
CSS-module class names on slot wrappers), or (c) duplicating other
tests' coverage.

Visual concerns (conditional padding, :has()-driven state styling) stay
verified by Storybook/Chromatic — Jest is the wrong tool for CSS
behavior.

Added three small prop-guardrail tests so every documented prop has at
least one direct test: forwardClickToControl, onClick, ref forwarding.

Subject: [PATCH 07/12] refactor: drop onClick and forwardClickToControl from
 ControlPresentation props
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Click handlers belong on the inner control, not on the wrapper. The
wrapper's click-to-focus behavior is internal — there's no real need
for consumers to disable it (forwardClickToControl) or hook into it
(onClick) for the wrap pattern.

The implementation still extracts onClick out of rest (via a type cast)
to compose with the focus-forwarding handler — this path exists only for
render-prop use, where Ariakit (or similar) forwards its own onClick to
the wrapper-as-trigger. Consumers of ControlPresentation directly won't
see onClick in autocomplete; TypeScript rejects passing it at call
sites.

Subject: [PATCH 11/12] refactor: narrow FieldChromeContainer's public surface

Replace `Omit<ComponentProps<typeof Box>, 'className'>` on FCC with
explicit `onClick` + `ObfuscatedClassName`. Move `display:flex`,
`align-items:center`, `overflow:hidden` into FCC's CSS. CP keeps its
loose public type (Box props) but only forwards `onClick` to FCC;
other Box props (maxWidth, etc.) are silently dropped pending a
follow-up CP API tightening.
