Accessibility work on the UI layer, all of it rooted in one structural gap: there were no form primitives, so every field was hand-assembled and every field got the same details wrong. Form primitives - components/ui/Field.tsx (Field/TextField/SelectField/TextareaField) and Button.tsx. Field generates the control id with useId and derives htmlFor from it, which is what makes the association impossible to omit rather than merely conventional. - 92 labels existed, 4 used htmlFor, and no input carried an id at all: a screen reader announced an unnamed edit box and clicking a label focused nothing. Now every label resolves to its control (0 unassociated), and the input class chain that appeared verbatim 85 times appears zero times. - Field also takes a render prop, so Lookup, CountryPicker and Picklist get the same wiring instead of a second, partial solution. - SearchInput replaces three hand-rolled copies of the icon-in-a-box search whose input had only a placeholder — not a label — and killed its own focus ring with outline-none and nothing in its place. - Toggle groups (workdays, reorg change type) became fieldsets with aria-pressed; colour alone was carrying the selected state. Comboboxes - Lookup and CountryPicker were text inputs with a div of clickable buttons underneath: typeable, but no keyboard path to a result and nothing telling a screen reader a list had appeared. Both now carry role=combobox, aria-expanded/controls/activedescendant and listbox semantics, with arrow keys, Enter and Escape. Escape stops propagation, or it would close the surrounding dialog along with the dropdown. Dialogs - useDialogFocus centralises what Modal and SlideOver each owed the keyboard and neither provided beyond Escape: focus into the dialog on open, Tab and Shift+Tab cycling within it, focus restored to the trigger on close. - SlideOver stays mounted for its transition, and aria-hidden does not remove anything from the tab order — so every closed panel was leaving invisible tab stops at the end of the page. `inert` fixes that. Route states - loading.tsx, error.tsx, not-found.tsx and global-error.tsx. Every page in the (app) group is server-rendered per request, so without loading.tsx a navigation showed nothing at all until the server answered, and a render error dropped the user on Next's own screen with no way back. Tests - 22 component tests (vitest jsdom project). Two of them found limits of the environment rather than of the code: jsdom implements neither `inert` nor scrollIntoView, so the inert test asserts the attribute and the missing scrollIntoView — which was taking the whole render down from inside an effect — is stubbed in the setup file.
