What changes

• Minimum sizes: each widget kind has a minimum and maximum width and a minimum height. Drag-resize, Narrower and the Height choices respect them; saved layouts are clamped on load.
• Organise (edit mode, desktop): splits the 12 columns into 1 to 4 lanes, stacks widgets in reading order, stretches each lane so the bottoms line up, then re-measures once after the widths change. One Undo step.
• New widgets: Calendar, Day progress, Journal, Goals, Next trip, Birthdays, Recent files. widgetTypes on the server lists them.
• Cards: icon chip, link to the widget's app, larger figures, softer surface; accents tint the card.
• Settings: one dialog per widget replaces the inline settings panel (which clipped the card) and Customise card.
• Gallery: icons, left-aligned text, widgets of switched-off apps hidden.
• Empty states: icon, title and an action for every widget, the empty dashboard and a crashed widget; setup actions open the widget's settings.

Checks

• test/integration/dashboards.spec.ts (now saves each new kind), lint, tsc -b, frontend build.
