 - Default grid cell padding: keep roughly 18px on the left edge and 12px on the right for standard cells (12px/9px for `auto-col-tight`) so text never hugs a column edge. Target the center + pinned containers so both regions stay aligned.
 - Overlays/menus: `rgba(8,12,24,0.96)` canvas, blurred backdrops, thin steel borders; bright typography; deep blue glass inputs; cyan confirm, mauve destructive accents.
 
+## Aurora Tabs (MagicUI Tabbed Interfaces)
+- Placement: sit directly below the hero title/subtitle band (8–16px gap). Tabs span the full width of the content column and anchor secondary hero metrics (see `Scheduling/Create_Job.jsx` and `Devices/Device_Details.jsx`).
+- Typography: IBM Plex Sans, `fontSize: 15`, mixed case labels (`textTransform: "none"`). Use `fontWeight: 600` for emphasis, but avoid uppercase that crowds the aurora glow.
+- Indicator: 3px tall bar with rounded corners that uses the cyan→violet aurora gradient `linear-gradient(90deg,#7dd3fc,#c084fc)`. Keep it flush with the bottom border so it looks like a light strip under the active tab.
+- Hover/active treatment: tabs float on a translucent aurora panel `linear-gradient(120deg, rgba(125,211,252,0.18), rgba(192,132,252,0.22))` with a 1px inset steel outline. This gradient applies on hover for both selected and non-selected tabs to keep parity.
+- Colors: base text `MAGIC_UI.textMuted` (`#94a3b8`). Hovering switches to `MAGIC_UI.textBright` (`#e2e8f0`). Always force `opacity: 1` to avoid MUI’s default faded text on unfocused tabs.
+- Shape/spacing: tabs are pill-like with `borderRadius: 4` (MUI unit `1`). Maintain `minHeight: 44px` so targets are touchable. Provide `borderBottom: 1px solid MAGIC_UI.panelBorder` to anchor the rail.

+- Interaction rules: tabs should never scroll vertically; rely on horizontal scroll for overflow. Always align the tab rail with the first section header on the page so the aurora indicator lines up with hero metrics.
+- Accessibility: keep `aria-label`/`aria-controls` pairs when the panes hold complex content, and ensure the gradient backgrounds preserve 4.5:1 contrast for the text (the current cyan on dark meets this).

 ## AG Grid Column Behavior (All Tables)
 - Auto-size value columns and let the last column absorb remaining width so views span available space.
 - Declare `AUTO_SIZE_COLUMNS` near the grid component (exclude the fill column).
