Drawer form — accessibility

Keyboard

Tab walks head → fields → footer in reading order; the first field usually takes focus through autoFocus on the input the screen marks.
The close control and both footer buttons are ordinary buttons: Enter and Space activate them.
Missing: Escape does not close the drawer (DrawerForm registers no key handler), and there is no focus trap — the drawer is part of the page, not a modal layer.
A disabled primary button is skipped by Tab, so a form that cannot be submitted has no keyboard path to an explanation; the reason must be in a field hint.

Panel: role="dialog" with aria-label = the title. It is deliberately not aria-modal, because the listing behind it stays live.
The head icon is decorative; the name comes from the title.
Each field is a <Field>, so the label is programmatically linked to the control and the hint is read with it.
The error sentence is plain text appended to the body — it is not a live region, so a failed save is silent for a screen reader, and it is not linked to any field.

Foundation ring from ds.css on the close control and the footer buttons; fields carry the input ring from ds.css.
Opening the drawer does not move focus by itself — the screen decides via autoFocus.
Closing returns nothing: focus is left where it was, which after a click on the close control means <body>.

Computed from packages/ui/src/tokens/tokens.css:

Title .pdr-top-name --ink-900 on --surface-100 = 17.59:1 light, 14.53:1 dark.
Field label and hint follow <Field>: label --label token, hint --hint (400 12px) in --fg-muted = 2.85:1 light, 3.63:1 dark — below AA for text.
Error sentence --critical-ink on --surface-100 = 5.37:1 light, 5.80:1 dark — passes AA.
Primary button: white on --accent = 4.44:1 light.
Focus ring --accent on --surface-100 = 4.44:1 light, 3.83:1 dark.

No Escape and no focus trap: the drawer behaves like part of the page even though it is announced as a dialog.
The failure message is not announced and is not tied to a field.
The error prop cannot carry a message, so the drawer cannot say why the save failed.
Hint text sits at 2.85:1 in light theme (system-wide --fg-muted limit).
