Tier 1Tier 1 · Web (www / app / auth). The full design system: our component library and the components.css recipe. This is the one tier where the recipe is the contract, native tiers take the tokens and nothing else.--radius-sm · --yellow-solid · --shadow-md · --component-bg-hover
01Folder picker: move destinationFolderPicker
Move and copy destination. Standard modal recipe; the tree body drops to --app-bg so rows read as content, not chrome. 32px rows, 20px indent per level, folder icons always --yellow-solid.
The selected destination takes --list-item-bg-active plus a trailing check. The current location stays visible but disabled: hiding it would make the tree look wrong. Keyboard: ↑↓ move, → expand, ← collapse, ↵ confirm.
