# PromptlyHash brand guide

## Brand idea

PromptlyHash should feel dependable, focused, and approachable. The hash symbol represents the application's purpose; the cyan check spark represents a verified result.

## Logo

The primary vector logo is `assets/PromptlyHash-logo.svg`. The Windows icon is generated by `tools/Generate-Icon.ps1`; keep both implementations visually synchronized. Use the full mark on light or neutral backgrounds.

- Keep clear space around the mark equal to roughly one quarter of its width.
- Do not stretch, rotate, recolor, outline, or add effects to the mark.
- Do not display the mark smaller than 24 px.
- For very small placements, keep the rounded square and hash readable; the verification spark may be omitted below 16 px.

## Typography

- Application UI: Segoe UI
- Headings: Segoe UI Semibold
- Hash values: Cascadia Mono, with Consolas as a fallback
- Use sentence case for buttons and headings.

## Voice

Use clear, calm English. Prefer short messages that state the outcome:

- “Hash matches — the file is verified.”
- “Hash does not match.”
- “Select a file to get started.”

Avoid unexplained security terminology and avoid implying that a matching checksum proves who created a file.

## Application naming

Write the base product name as **PromptlyHash**, without a space. Use the
versioned form **PromptlyHash - vX.Y.Z** for installed application window
titles, Start menu shortcuts, installation folders, and Windows installed-app
entries. This distinguishes side-by-side installations without changing the
product name.

The short description is:

> Generate and verify file checksums with confidence.
