description	Enforce PlanWiki's updated UI shape language shared `components/ui` primitives default to `rounded-sm`, while composed workspace surfaces, widgets, badges, cards, and controls stay `rounded-none` unless the user explicitly asks for more rounding.

Apply this skill when building or restyling PlanWiki UI.

Core rule

• Default shared primitives in components/ui to rounded-sm.
• Default composed PlanWiki surfaces outside components/ui to rounded-none.
• Treat square corners as the project style for workspace pages, widgets, cards, badges, chips, stats, tables, controls, and overlays that make up the product UI.
• Do not introduce rounded, rounded-md, rounded-lg, rounded-xl, or pill-shaped treatments unless the user explicitly requests them.

What to preserve

• Keep the existing flat, minimal visual language.
• Prefer borders and spacing over decorative shape styling.
• Keep circular affordances that rely on rounded-full for their function or iconography.
• If a component comes from a shared UI primitive with rounded-sm defaults, override it locally with rounded-none where it appears in PlanWiki surfaces.

When working on existing files

• Remove accidental corner rounding from wrappers and internal elements.
• Check usage sites, not just base components. A square feature surface can still be overridden by rounded-md, rounded-lg, or rounded-full in feature code.
• Keep sidebar behavior and established layout patterns intact unless the user asks for structural changes.

Quick checklist

• components/ui: rounded-sm by default
• Cards: square at usage sites unless the user asks otherwise
• Widget shells: square
• Badges/chips/status pills: square
• Buttons in workspace UI: square unless existing design requires otherwise
• Inputs, textareas, tables, dropdown surfaces: square where they participate in the workspace visual system

If there is any ambiguity, use rounded-sm in components/ui and rounded-none everywhere else.
