 5. **Grid layouts:** `align-items: start;` (NOT center/stretch) to prevent column stretching at different heights
 6. **Max-width constraint:** Wrap pages in `.page-wrapper { max-width: var(--ks-content-max); margin: 0 auto; }` to prevent 2560px+ distortion
 
+#### Page Structure Rule: NO Page Footers
+**CRITICAL:** Footer sections must NOT exist in PageLayout. All footer functionality (buttons, status, actions) must be moved to:
+- **Primary actions:** `<template #actions>` (header right side) — e.g., Help, AI Suggest
+- **Command bar:** `<template #commandBar>` — e.g., Save, Reset, Approve buttons
+- **Status info:** `<template #summary>` — e.g., Watermark, Owner, System status
+
+**Rationale:**
+- Footers waste viewport space at bottom (max ~48px with padding)
+- Single-screen principle: all interactive controls should be in view without scrolling
+- Mobile UX: footer buttons are hard to reach (thumb-friendly buttons are top/sides)
+- Information density: header/command-bar can convey status without extra rows
+
+**Example Migration:**
+```vue
+<!-- ❌ DON'T: Use footer -->
+<PageLayout title="Market Data Import">
+  <template #footer>
+    <button @click="reset">초기화</button>
+    <button @click="schedule">수집 예약</button>
+  </template>
+</PageLayout>
+
+<!-- ✅ DO: Move to command bar -->
+<PageLayout title="Market Data Import">
+  <template #commandBar>
+    <button @click="reset">초기화</button>
+    <button @click="schedule">수집 예약</button>
+  </template>
+</PageLayout>
+```
