Visual registers span the full catalog extreme: Block is among the hardest and most geometric sub-styles in the entire catalog, while Stickies Colors is the friendliest and most playful sub-style available — no other family contains sets this far apart in emotional register. Four of the eleven sets (Guidance, Block, Nasty, Typeface) carry free CC BY 4.0 commercial licenses.

# Streamline Vault

Eleven specialist sets sold separately from the main Streamline families, each covering a domain that general-purpose UI families do not — wayfinding pictograms, luxury ecommerce, Bauhaus solids, sticker aesthetics, flat illustration, adult brand content, letterforms, and iOS mockups. Visual registers span the full catalog extreme: Block is among the hardest and most geometric sub-styles in the entire catalog, while Stickies Colors is the friendliest and most playful sub-style available — no other family contains sets this far apart in emotional register. Four of the eleven sets (Guidance, Block, Nasty, Typeface) carry free CC BY 4.0 commercial licenses. No Vault set functions as general-purpose UI navigation; all are specialist supplements designed to be layered on top of a chosen primary family for a specific domain need.

17 sets

Licenses: Free, Commercial

## Fit & Recommendation

### Best fit when

Recommend Vault when the primary UI icon system is already established and a specialist layer is needed for a specific domain; when a particular context — wayfinding, luxury ecommerce, Bauhaus density indicators, consumer illustration, gamification rewards, adult brand identity, or letterform identifiers — requires purpose-built coverage that general-purpose families do not address; when free commercial licensing matters (Guidance, Block, Nasty, and Typeface are CC BY 4.0).

Fit score increases when: the project has a clearly defined non-UI icon need (venue maps, sticker achievement rewards, product feature illustration); the primary icon family is already chosen and the team is selecting a supplement; the visual register of a specific Vault set closely matches a particular product surface (Platinum for a luxury PDP, Stickies for a gamification screen, Guidance for a venue or civic app).

### Avoid when

- General-purpose UI navigation is needed — no Vault set functions as UI chrome; all require a primary family alongside them
- Visual consistency across all icon contexts is required — the eleven sets span incompatible visual registers and cannot be used interchangeably
- Multiple Vault sets are being considered on the same surface — each has a strong distinct register that conflicts with others
- Kameleon is being evaluated for design-literate B2B or tech audiences — the flat illustration style is dated and will undercut credibility
- iOS 14 is needed for long-term brand materials — the set ages with Apple's design language and requires periodic refresh
- Nasty is being deployed without explicit adult content review — it is not suitable for general audiences, regulated industries, or any user base under 18
- Only Block has full dark-mode native performance; all other sets are conditional or context-dependent — verify rendering in dark contexts before deploying

### Primary use cases

- **Guidance**: Venue navigation, accessibility documentation, civic and healthcare digital products
- **Platinum**: Luxury ecommerce, premium DTC brand marketing, editorial product pages
- **Block**: Data-dense developer tooling, compact status indicators, Bauhaus design identity systems
- **iOS 14**: Device mockup presentations, app store marketing, iOS tutorial content
- **Stickies**: Consumer onboarding, gamification rewards, youth-targeted app marketing
- **Kameleon**: Feature section illustration, consumer landing pages, social media marketing
- **Nasty**: Adult irreverent brand identity, Halloween campaigns, counter-culture brand content
- **Typeface**: Lettered category identifiers, step indicators, avatar initials in rounded Streamline systems

### Secondary use cases

- **Guidance**: Print signage alongside digital deployment (CC BY 4.0 permits both)
- **Block**: Compact density modes in large enterprise design systems
- **Kameleon**: Investor pitch decks for consumer-facing products
- **Typeface**: Keyboard shortcut indicators, alphabetical navigation in directory interfaces

## Visual & Technical Specs

### Visual properties

Each set has its own distinct construction. The unifying principle is **purpose over style** — every set is designed to do one thing well.

- **Geometry**: Ranges from strict geometric (Block) to organic cartoon (Nasty) — no shared language across sets
- **Detail density**: Low to medium across all sets
- **Deployment**: Most sets are designed for display sizes or context-specific use, not dense small-size UI chrome

### Emotional Scores

The Vault family average is less meaningful than for any other family — the eleven sets span the full catalog emotional range, from the most playful register in the catalog (Stickies Colors) to among the most severe (Block). The average is an artifact of aggregation, not a guide to any individual set. Scores vary dramatically across sets on every axis. Always check the individual set scores before making a recommendation — the family-level average provides no reliable indication of what a specific Vault set will communicate.

**Emotional scores**

Guidance – Free — Somewhat cold. Somewhat soft, as the 1px thin strokes and organic human figure forms prevent the hardness of geometric sets. Somewhat cold on friendliness — wayfinding conventions are inherently formal and directive. One of the more serious sub-styles in the catalog. Somewhat human-feeling — human figures are the defining characteristic, making this the most human construction in the Vault group's institutional sets.

Platinum — Somewhat warm. Among the softest sub-styles in the catalog — 1px hairline is the softest possible visual weight at this grid size. Near neutral on friendliness. Near neutral on playfulness leaning slightly serious. Somewhat human-feeling. Hairline restraint communicates quiet luxury through what is absent rather than what is present.

Block – Free — One of the colder sub-styles in the catalog. Among the hardest sub-styles in the catalog — fully opaque fills with sharp rectangle corners produce among the hardest visual weight in the catalog. Somewhat cold on friendliness. One of the more serious sub-styles in the catalog. One of the more mechanical sub-styles in the catalog. Bauhaus construction is the definitive machine-aesthetic in design history.

iOS 14 — One of the warmer sub-styles in the catalog. One of the softer sub-styles in the catalog. Among the friendliest sub-styles in the catalog. One of the more playful sub-styles in the catalog. Somewhat human-feeling. Full-spectrum colour in iOS superellipse containers reflects the casual consumer-entertainment vocabulary of smartphone home screens.

Stickies Duo — Among the warmest sub-styles in the catalog. Among the softest sub-styles in the catalog. Among the friendliest sub-styles in the catalog. Among the most playful sub-styles in the catalog. Among the most human-feeling sub-styles in the catalog. The physical sticker aesthetic with organic blob shapes and gloss highlights signals tactile delight rather than digital polish.

Stickies Colors — Among the warmest sub-styles in the catalog — tied for the warmest alongside Plump Line and Plump Pop at the minimum warmth score. Among the softest sub-styles in the catalog. Among the friendliest sub-styles in the catalog — tied for the most friendly/playful in the entire catalog on both friendliness and playfulness. Among the most human-feeling sub-styles in the catalog — tied for the most human-feeling alongside Freehand and Nasty - Free. Hot pink, yellow, and cyan on irregular blob forms with gloss highlights maximise warmth, colour expressiveness, and physical tactile quality simultaneously.

Kameleon Colors — One of the warmer sub-styles in the catalog. One of the softer sub-styles in the catalog. Among the friendliest sub-styles in the catalog. One of the warmer sub-styles in the catalog on playfulness. Somewhat human-feeling. Warm palette in circular containers produces an illustrative, consumer-facing register with strong visual energy at display sizes.

Kameleon Duo — Somewhat cold. One of the softer sub-styles in the catalog. Somewhat friendly. Somewhat playful. Somewhat human-feeling. The blue tonal system adds structured order that the warm-palette variants lack, making this the most professional and controlled Kameleon variant.

Kameleon Pop — One of the warmer sub-styles in the catalog. Somewhat soft. One of the friendlier sub-styles in the catalog. One of the warmer sub-styles in the catalog on playfulness. Somewhat human-feeling. Dark symbols on vivid rotating fills create the highest colour energy and graphic boldness in the Kameleon range.

Nasty - Free — Somewhat warm. One of the softer sub-styles in the catalog. One of the friendlier sub-styles in the catalog. One of the warmer sub-styles in the catalog on playfulness. Among the most human-feeling sub-styles in the catalog — tied for the most human-feeling alongside Freehand and Stickies Colors. Expressive organic cartoon lines read as drawn, not engineered, giving dark subject matter a playful rather than threatening visual register.

Typeface - Free — Somewhat warm. One of the softer sub-styles in the catalog. Somewhat friendly. Somewhat playful. Somewhat human-feeling. Monolinear geometric sans with rounded terminals scores neutrally across all five axes, matching the visual language of Core, Flex, and Streamline 3.0.

### Size behavior by set

| Set | Min size | Best range |
|-----|----------|------------|
| Guidance | 28px | 28–96px |
| Platinum | 20px | 24–48px |
| Block | 14px | 14–24px |
| iOS 14 | 32px | 48–96px |
| Stickies | 24px | 28–64px |
| Kameleon | 32px | 40–96px |
| Nasty | 32px | 48–96px |
| Typeface | 14px | 16–48px |

Block and Typeface are the only Vault sets suited for small-size UI contexts.

## Pairing & Compatibility

### Typography pairing by set

- **Guidance** (institutional/wayfinding): Inter, Roboto, Helvetica Neue, Frutiger, Aktiv Grotesk
- **Platinum** (luxury editorial): Cormorant Garamond, Söhne, Plus Jakarta Sans Light, Neue Haas Grotesk Light
- **Block** (Bauhaus geometric): IBM Plex Sans, Barlow Condensed, Neue Haas Grotesk, Space Grotesk
- **Stickies, Kameleon** (consumer warm): Nunito, Fredoka, Poppins, DM Sans
- **Nasty** (irreverent/dark): Permanent Marker, Bebas Neue, Helvetica Neue (ironic contrast)

Match typography to each set's individual register — there is no single type recommendation that spans all eleven sets.

### Mixing guidance

**Recommended with**: Any primary family as the main UI system — Vault sets are specialist supplements, not replacements.

**Possible with normalization**:
- Guidance alongside any primary family — strictly for wayfinding and accessibility contexts
- Typeface alongside Core, Flex, or Streamline 3.0 — matching monolinear rounded DNA
- Block alongside Sharp or Cyber — compatible technical authority register

**Avoid mixing**:
- Using Vault sets as general UI navigation icons — category error for all eleven sets
- Mixing multiple Vault sets on the same surface — each set has a strong distinct register

**Key rule**: Vault sets occupy a specialist functional layer; a primary UI family handles all navigation, chrome, and controls. Never place a Vault set alongside a primary family icon in the same component.
