## Product direction

ECM Park Services v3 is a clean rebuild. Legacy ECM pages may inform module names, categories, order, and workflows, but legacy UI styling and page-specific CSS should not be copied directly into v3.

## Shell rules

- Use the A26 Web Design System for tokens, typography, material behavior, buttons, toolbar, list rows, symbols, dividers, groups, and pane layout.
- The primary sidebar owns top-level navigation.
- The secondary pane owns module-specific lists and actions.
- The tertiary pane owns selected item detail.
- Compact/mobile layout should behave like a pane hierarchy, not a squeezed desktop layout.
- The sidebar should feel like its own screen on mobile.
- No login or legacy module logic until explicitly added.

## A26 behavior to preserve

- Border-only symbol backplates in grouped/list contexts.
- Active row and active button symbols match active text foreground.
- Inset list dividers in grouped lists.
- No list dividers in sidebars.
- Theme-aware borders and text/icon colors.
- System-font stack only; do not package or distribute Apple font files.
