Harborline Operations: three page studies

Identical six-shipment fixtures, search/filter controls and exception detail. Open a study below; use the Preview size controls to compare desktop 1280px, tablet 768px and phone 375px. Each study includes list/detail, filter-sheet and alternate-state illustrations.

These are static, noninteractive design artifacts, not an application. Narrow screens show list and detail sequentially for comparison, not as a proposed long single workflow. Named typography is proposed; rendering uses local system fallbacks without external font services.

Research provenance: the prior assistant inspected both supplied references through Mobbin MCP. No fresh reinspection or reference-fidelity claim is made. Direction selection approves neither product milestone.

Each direction retains all six fixtures, selected HL-1042, filter sheet, validation, unavailable detail, no data, no results, local loading, saved/unsaved, read-error and reset-confirmation illustrations. Screenshots establish appearance only—not working behavior, keyboard access, persistence or measured accessibility.

Separate product milestone proposals remain unapproved and undelivered. No commercial acceptance or public deployment exists.
