The idea

The idea

A prompt that resolves into a word.

insigle = sigle (a mark) + insigne (a badge). The logo :l is a terminal prompt (:) and a living cursor (l); the prompt resolves into the word, the dots become the dots of the i's.

That is the product: agent attention turned into brand presence that is legible, controllable, and provable. Nothing magic, nothing wasted.

:l mark insigle

The reveal: the prompt :l appears, the cursor goes live, the two dots fly up to dot the i's, then the word settles mono. Motion assets — mark-live.svg · wordmark-live.svg · mark-loading.svg. Electric indigo is motion-only; the static logo is never coloured.

Visual world

Visual world

Evidence, not atmosphere.

Imagery is operational proof or a chapter marker — never decoration. One image per spread, full-bleed, in a single indigo duotone so every source reads as one material world. Built structure and circulation — the system that routes agent demand, never a mood.

Logo system

Mono at rest. Electric only in motion.

The :l is the only proprietary mark — a colon prompt centred on a cursor. Always the official files below, never a redrawn shape. Static = monochrome (ink on light, paper on dark — see the two tiles); the electric indigo appears only while the mark is alive.

Do — use the canonical files from logo/. Don't — redraw the :l, round the ends, or colour the wordmark. Motion variants: mark-live.svg / wordmark-live.svg.

In product navigation: the expanded rail shows the full insigle wordmark; collapsed, it reduces to the :l mark — the wordmark resolving back to its cursor (the reveal, in reverse).

Colour

Colour

Quiet greys. One UI accent. Electric only in motion.

Two indigos, two jobs. --brand-electric is a brand / motion constant — logo, reveal, export — never a UI colour. The UI accent (de-neoned) is the semantic signal for active / focus / selection. ~95% of every surface stays indigo-tinted near-monochrome; components consume semantic tokens, never raw hex. Authoritative hex: PALETTE.generated.md.

Inter speaks. Space Grotesk signs.

Type

Inter — all UI, body, headings. Space Grotesk — wordmark lockup only. Geist Mono — code, IDs, tabular figures.

Icons

IconPark outline (48-grid, stroke 3.2, currentColor). Never for :l / wordmark. Map: iconpark-mapping-spec.md.

Motion

Productive 80/120/180ms, no bounce. Expressive reserved for the logo reveal. prefers-reduced-motion respected.

The one smile lives in the reveal, the loader, a rare empty state — never smileys in controls, a mascot, or :l as a gimmick in every component.

Decks — two themes, one system: Light Primary (client handoff) · Dark Secondary (premium). 1920×1080; eyebrow neutral UPPERCASE; one accent per slide (light / dark); chrome = Confidential + source (mono) + :l & page (cover unnumbered → 01–06); duotone imagery (light-duo / dark-duo + scrim); 7-day stacked chart, table figures in Inter. Spec: orchestration/deck-style-model.md.

Keeps it serious
Don't
  • gradient backgrounds; orbs, bokeh, glassmorphism, "AI sparkle".
  • cards everywhere to fill; neural-net illustration.
  • emojis in controls; Space Grotesk as UI font; #3B30E8 in static chrome.
  • a deck hue as a UI state; unsourced big numbers.
Build & handoff
  • Truth = spec.jsonbuild_tokens.pytokens.css/json / PALETTE.generated.md.
  • Logos = logo/; imagery register = assets/images/image-register.md (CC0 / public-domain only).
  • Figma: Primitive / Semantic (light+dark) / Brand + components + deck masters.
  • QA before delivery: all 42/42 contrast pairs pass (light + dark); the electric indigo stays in motion/logo only; screenshot both themes.
