<p>Core is the Helvetica of icons. Each icon is stripped to its essential form and has generous inner spacing. The Line variant offers a clean, minimalist approach with consistent line weights.</p>

Core Line

**Summary**: The definitive neutral UI icon — 1px rounded stroke on a 14px grid, stripped to essential form, designed to be invisible infrastructure that serves content rather than demanding attention. Scores at a genuine midpoint on its human↔mechanical character, achieved by no other sub-style in the catalog, and is one of the softer sub-styles available, reflecting a construction so minimal that almost no visual personality remains. The tone signals pure infrastructure: "we are here if you look; we won't demand that you do." Best for productivity tools, component libraries serving diverse audiences, admin panels, and any product with a strong typographic or illustration identity that must not compete with its icon layer.

## Fit & Recommendation

### Primary use cases

- Universal UI navigation and controls where icons should be invisible infrastructure
- Any product that values neutrality above personality — icons adapt to the surrounding design system rather than imposing character
- Productivity tools (task managers, note apps, calendar apps) where cognitive clarity is primary
- Component libraries needing icons that work alongside any colour token system without clashing
- Products with very strong typographic or illustration identity — Core Line will not compete
- Internal tools and admin panels that prioritise clarity without brand personality

## Brand & Cultural Identity

### What it communicates

> "We are infrastructure. You won't notice us, and that is the point."

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | 1px |
| Fill | None |
| Corner treatment | Rounded caps and joins throughout |
| Color | Monochrome |

### Emotional Scores

Core Line is somewhat warm and one of the softer sub-styles in the catalog — the 1px stroke on a 14px grid produces one of the lightest, most unobtrusive icon constructions available. It is somewhat friendly and somewhat playful. On its human↔mechanical character, it sits at a near-neutral midpoint — the only sub-style in the catalog to land at this precise balance point, where rounded ends give a slight human quality and strict minimal construction gives a slight systematic quality in equal measure.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Inter — the pairing is almost tautological; two neutral humanist systems designed for UI at the same level of philosophical reduction
- **Alternative**: DM Sans — slightly more personality than Inter, compatible with Core's rounded geometry
- **Editorial**: Neue Haas Grotesk — Swiss neutrality in type matches the stripped Swiss construction in icons
- **Body**: Source Sans Pro or Mulish — clean, screen-optimized, non-competing
- **Avoid**: Display fonts with strong personality (Syne, Playfair Display) — contrast between expressive type and invisible icons creates incoherence
