Use the exact delivered masters described on the Logo system sheet. Formal colors and their measured uses are on the Color sheet. Display Space Grotesk, body Geist, and mono Geist Mono are the declared type families.
Where each asset belongs: The Asset catalog lists verified marks, lockups, icons, and platform deliveries by intended surface and size.
Keep delivered artwork geometry unchanged. The Usage limits sheet lists every source rule.
Do not rotate, skew, stretch, outline, bevel, or add glow.
Mark: The current primary mark is the exact prompt and cursor geometry from the shipped favicon. Anchor Blue draws the prompt and Interval Mint draws the cursor. Pair it with the outlined go-schedule wordmark in horizontal and stacked lockups.
Color: Night, Panel, and Line provide the infrastructure surface. Anchor Blue carries identity, links, focus, and exact run points. Interval Mint carries recurrence and success. Hold Amber and Stop Red remain scarce operational signals.
The current primary mark is the exact prompt and cursor geometry from the shipped favicon. Anchor Blue draws the prompt and Interval Mint draws the cursor. Pair it with the outlined go-schedule wordmark in horizontal and stacked lockups. Mark means symbol; wide and stacked lockups are separate. Clear means transparent; light and dark name the viewing surface. See Asset Language in the main manual.
One clear-space unit on every side: 54 units on the 512 × 512 canvas, 10.5 percent of artwork width. No text, border, icon or crop enters that band.
| mark | 24 px |
| horizontal | 160 px |
| stacked | 96 px |
| wordmark | 120 px |
Below 32 px the reduced master takes over. It ships as its own file. Do not rasterize the full mark down at runtime.
| Lockup | Mark height | Gap | Alignment |
|---|---|---|---|
| Horizontal | 160 units | 34 units | Optical center |
| Stacked | 1.80C | 0.45C | Centered on wordmark ink width |
The horizontal row records its approved master composition. C is the outlined wordmark cap height used by the stacked lockup. X is the clear-space unit declared above. Keep one X clear around every master and never resize the mark and wordmark independently.
These are the exact source usage rules for this identity. The preceding Logo system sheet gives measured sizes and clear space.

Night, Panel, and Line provide the infrastructure surface. Anchor Blue carries identity, links, focus, and exact run points. Interval Mint carries recurrence and success. Hold Amber and Stop Red remain scarce operational signals.
The bright accent #58A6FF measures 2.38:1 on the light reading surface and is never text there. The light token block substitutes #1160C6 at 5.62:1 automatically. The legal foreground on an accent fill is #000000 at 8.31:1. Every fill token in brand.json carries its measured foreground.
| Color | Means |
|---|---|
| Accent | Primary value, selection, links, focus |
| Orange | Needs attention, threshold exceeded |
| Destructive | Failed or timed out. Always with text. |
The emphasis and failure colors may not be reliably separable under deuteranopia. That is acceptable only because state is never carried by color alone: every state ships a written label.
Chart colors serve data visualization. Brand applications use the identity accent and the neutral surfaces. Each chart color is derived from the identity accent and measured against its surface so every entry clears 4.5:1.
Lightness is calculated separately for dark and light surfaces. Data charts also use labels or shapes; hue alone does not carry meaning.
| Series | Dark | Light |
|---|---|---|
| chart-1 | #4D9BF3 | #1160C6 |
| chart-2 | #C179C9 | #933B93 |
| chart-3 | #E07655 | #A83F00 |
| chart-4 | #A19E1B | #666B00 |
| chart-5 | #00B199 | #00756A |
Series order is fixed: chart-1 is always the primary measurement. Never reorder to make a chart look better. Never introduce a sixth color; past five series, switch to a form that does not depend on hue. A series never uses the semantic emphasis or failure colors, because those carry state.
go-schedule uses three approved type families. Space Grotesk handles display text, Geist handles interface and reading text, and Geist Mono is reserved for literal command blocks.
| Function | Typeface | Weights |
|---|---|---|
| Display, headings | Space Grotesk | 500, 700 |
| Body, interface | Geist | 400, 500 |
| Literal code blocks | Geist Mono | 400 |
| Axis | Value |
|---|---|
| Radii | 6 / 8 / 12 / 16 / pill |
| Spacing | 4 8 12 16 24 32 48 64 96 120 |
| Focus | 2px ring at 2px offset |
Only the listed local faces are approved. Any other weight makes the renderer synthesize a faux bold, which prints badly and forces outlined glyphs into exported PDFs. Courier Prime is used only for literal command blocks.
| Token | Size | Tracking |

| display-xl | 72 | -0.030em |
| display-lg | 56 | -0.025em |
| display-md | 40 | -0.020em |
| display-sm | 28 | -0.015em |

go-schedule declares ShruggieTech parentage. Palette sharing and typography are separate explicit choices. The approved mark and colors remain this brand's own source decisions.
The approved mono family, uppercase, positive tracking. Visually subordinate and outside the logo clear space. Never a combined parent-product lockup.
The catalog lists installable theme and component items. For offline fonts, copy nextjs/fonts.ts and fonts/ together from the kit.

| Decision | Declaration |
|---|---|
| Ownership | ShruggieTech owned |
| Parent | ShruggieTech |
| Palette | Shared house emphasis and action, explicitly selected |
| Typography | House families |
Colors for actions and states are distinct from formal identity artwork. A shared HEX is a deliberate choice; meaning also uses words, icons, outlines, or state attributes.
| Color | HEX | Source | Use |
|---|---|---|---|
| Schedule anchor | #58A6FF | brand.accent.bright | Primary identity anchor |
| Interval Mint | #62D9B7 | brand.logo.role_colors.color.interval | Approved interval segment in the mark |
| Application | Colors and artwork | Use |
|---|---|---|
| Go Schedule mark | primary, interval in logo.full | Anchor blue with the approved interval segment |
Correct: use Schedule anchor (#58A6FF) in approved identity work; pair the Warning cue (#FF5300) with warning text and icon. Misuse: a lone identity swatch as the only warning signal.
