 - Prefer one clear value over unsupported detail. Hide subscription fields the provider does not supply.
 - Keep client UI compact and calm. Do not introduce dashboard cards, decorative chrome, or admin-console density.
 - Do not use a modal, popup, or blocking backdrop unless the user explicitly asks for one. Prefer inline disclosure or a non-modal layer that preserves the main screen.
+- When the owner explicitly chooses modal treatment for critical confirmations, reuse one accessible full-screen confirmation popup: blur and block the background, reveal from center, then stage text and actions.
 - Avoid borders, divider lines, and framed regions by default. Build hierarchy with spacing, typography, subtle surface changes, light, and depth; use a line only when it communicates an essential state.
 - In client-side editors, prefer flat text controls and accessible custom pickers over browser-native menus when the native surface breaks the visual language. Do not append another blank row until the current row is complete.

+## Critical confirmation popup

+- Reserve the blocking popup for explicit destructive or data-loss confirmation. It must cover the viewport, make the background inert, and use `alertdialog` with `aria-modal`.
+- Fade and blur the backdrop first, resolve the popup from the center, then reveal its title, description, and actions in a short sequence.
+- Put initial focus on the safe action, trap Tab within the popup, let Escape and backdrop click choose the safe action, and restore the invoking focus on close.
+- Reuse the same component and motion vocabulary for every critical confirmation. Reduced motion presents the final state immediately.

 - Use one fast translucent cloud treatment for explanatory tooltips. Place the cloud above its target with strong enough contrast to survive busy content beneath it.
 - Keep a tooltip as a sibling of the animated icon/button it describes. A tooltip must never rotate, glow, blur, scale, or move with the control.
-- Use inline confirmation for destructive subscription removal. Explain that VPN stops and proxy-dependent applications lose connectivity until a new subscription is configured.
+- Use the shared full-screen critical confirmation popup for destructive actions and unsaved-data exits. Keep the centered surface flat, with hierarchy from blur, spacing, type, and staged motion rather than borders or rounded cards.
 - Animate physical icon parts when their function suggests it, such as lifting a trash lid on hover, while keeping hit areas and nearby text fixed.
 - Keep advanced client editors flat inside their side layer: rows, notes, selectors, and actions should not become nested cards, bordered fields, or raised buttons. Use spacing, type, focus light, and state color for hierarchy.
