   3. **Multi-Selection Batch Toolbar (Grid Top/Bottom Selection Bar)**: Activated conditionally upon multi-row selection for **Bulk Actions** (e.g., `선택 일괄 승인(3)`, `선택 일괄 삭제`).
 - **[CRITICAL IRON RULE] Standardized Loading Skeleton Rule**: ALL screen-level and section-level data loading MUST render animated `SkeletonLoader` (shimmer mode) matching the expected layout (e.g. `skeletonType="table"` for grids, `skeletonType="card"` for forms/summaries) through `QueryStateBoundary`/`StandardScreenBoundary`. Static text ("불러오는 중...") or empty screen placeholders during loading states are STRICTLY PROHIBITED.
 - **[CRITICAL IRON RULE] Standardized Empty Data State Rule**: When zero records or empty dataset states occur, ALL grids, lists, and summary cards MUST render standard `EmptyStatePlaceholder` component (`📭` icon, clear title, descriptive helper text, and optional recovery action button). Blank white spaces or plain `<p>데이터가 없습니다</p>` text tags are STRICTLY PROHIBITED.
-- **[CRITICAL IRON RULE] Standardized UI Component Scale & Density Rule**: ALL UI components (grids, inputs, buttons, select, date fields, cards) MUST strictly inherit central Design System Tokens (`tokens.css` / `base.css`). Custom inline height/font overrides are STRICTLY PROHIBITED. Grid header height (`30px`), row height (`28px`), control height (`28px`), and grid font size (`12px`) MUST be universally uniform across all screens.
+- **[CRITICAL IRON RULE] Standardized Form & Filter Control Width Rule**: ALL form & filter controls MUST adhere to central default width tokens (`tokens.css` / `base.css`). Controls MUST NOT stretch to 100% full width inside filter bars unless explicitly grouped in full-width grid layouts:
+  1. **Select / Dropdown (`select`, `.p-select`, `.ks-select`)**: Default width `--ks-control-width-select` (`160px`).
+  2. **Search Input (`.search-input`)**: Default width `--ks-control-width-search` (`220px`).
+  3. **Date Picker (`input[type="date"]`)**: Default width `--ks-control-width-date` (`140px`).
 - **[CRITICAL IRON RULE] Standardized Grid Row Numbering Rule**: Unless explicitly disabled (`showRowNumber: false`), ALL data grids MUST automatically prepend a pinned left `No.` column rendering 1-indexed sequential row numbers (`node.rowIndex + 1`) centered with `54px` fixed width.
 - **[CRITICAL IRON RULE] Standardized Grid Theme, Zebra Stripes & Color Palette Rule**: ALL data grids MUST inherit central Theme Color Tokens (`tokens.css`) without ad-hoc inline overrides. Grids MUST enforce:
   1. **Header Background**: Premium Header Gray `#f1f5f9` (Dark Mode: `#1e293b`), font-weight: `700`.
