Brand icons
The Nexus ReGen brand icon system: the arrow emblem with a legibility weight scale, the logo variants coloured by token, and a Google-style product app-icon family. The arrow always points down-left — never flip, mirror or rotate it; and Nexus yellow is never used as text on white.
Emblem weights
The source emblem renders as a thin keyline, which reads too light when small. NxEmblem adds a weight scale — regular (bare keyline), medium and bold (thickened by a same-colour stroke), and solid (the filled silhouette). Shown at 64px, then 24px and 16px to prove small-size legibility.
Logo variants
The reworked NxLogo, drawn inline and coloured by token: navy emblem + navy wordmark on light; accent-yellow emblem + white wordmark on dark (the fixed behaviour — yellow arrow, white text, never yellow-on-white). On a solid navy band the monochrome escape hatch collapses the whole mark to one colour.
App icon family
Google-style product icons: the arrow on a rounded tile, tinted by a fixed brand tone with a small glyph top-right. These are identity artefacts — their hexes never flip with light/dark or the brand variant. Shown at 64px, then again at 28px in a mock dock to prove the family stays coherent when small.
Favicons & app tiles
For favicons use the bare bold-keyline emblem (navy on light, yellow on dark) — the outlined house style, thickened to stay crisp at 16px. For PWA/maskable icons use a padded tile so the emblem clears the platform's circular safe zone.
Platforms crop maskable icons to a circle. NxAppIcon centres the arrow well within the ~80% safe zone (dashed), so it survives the crop on Android, iOS and Windows tiles. Use shape="circle" when a round icon is wanted outright.
Download
Each app-icon card above has a download button that serialises its live SVG node to a Blob and saves it as <name>-icon.svg — entirely client-side, no server round-trip.
The download uses XMLSerializer on a clone of the rendered node, wrapped in a Blob — so what you save is exactly the vector shown, at its native resolution.
