Problem Solving & Design B

The grouping logic is well-structured and tested, but form controls lack accessible labels and ARIA attributes, leaving the interface incomplete for assistive-technology users.

• +The chip toggle pattern visually hides the radio input while forwarding focus-within to the visible label, preserving keyboard operability without removing the input from the tab order.
• +Delicates are collapsed into a single pile regardless of color category, which matches the real-world laundry rule that fabric sensitivity overrides color sorting.
• -Form controls for color category and fabric type use visually-hidden radio inputs but no visible label element associates with them by id, so screen readers cannot announce what each chip group represents.
• -No ARIA attributes (role, aria-label, aria-checked, aria-live) are present on the chip groups or load pile grid, so dynamic updates to the load list are not announced to assistive technology.

Completeness C

Core sorting, removal, and summary features are all present and wired together, but input validation, empty states, and error surfacing are absent.

• +Items are grouped and sorted deterministically — delicates first, then by color and fabric — and the loads update via useMemo whenever the item list changes.
• +The summary bar receives the derived load count and total item count directly from App state, keeping it always in sync.
• -There is no input validation on the item name field — a blank or whitespace-only name can be submitted without any feedback to the user.
• -No empty state is rendered when the item list or load grid has no entries; the brief implies something deliberate should appear before any items are added.
• -No loading state exists anywhere in the UI, and no error handling wraps operations such as crypto.randomUUID() that could theoretically fail in restricted environments.

Technical Craft B

The codebase is cleanly modularised with shared design tokens, typed domain models, and a thorough automated test suite covering grouping logic edge cases.

• +All design values — colours, spacing, typography, radii, and motion easing — are declared as CSS custom properties in a single tokens file and consumed everywhere else by reference.
• +The groupItems test suite covers the worked example, edge cases, and determinism, asserting on labels, counts, member identity, and sort order.
• +Entrance animations respect the prefers-reduced-motion media query by disabling keyframe animations and transitions for users who have opted out of motion.
