Patterns

Multi-element behaviours: search input, view toggle, filter chips, empty / error states, sticky sidebar.

Search input (landing hero)

Distinctive composite control on the landing page: search icon + input + submit button, all inside a single bordered wrapper that highlights on focus-within.

<LandingSearch ... /> focus-within ring in --primary

View toggle (Gallery / List / Map)

Always present on results pages regardless of result composition. URL captures the current view.

Filter chips (active filters)

Active filter representation on search-result pages. Each chip has a remove button with a clear aria-label.

Region: Jura Period: Lower Devonian Type: Fossil
<Chip ... removeLabel="...">

Empty states

Typographic, calm, action-oriented. Never illustrations. Never patronising microcopy.
