## Overview

FastFetch Dynamic Logo Theme Pack combines JSONC display configurations, logo assets, and a PowerShell command wrapper. The main workflow is a user invoking `ff`, which selects or accepts a logo and configuration, then runs FastFetch to display it in a terminal. The README also documents ASCII, static-image, animated-image, and Sigil modes. Relationships shown here come from README statements; no source excerpts were available to verify implementation details.

Main entry points: [`ff.ps1`](https://github.com/klein-3000/fastfetch/blob/main/ff.ps1) (Sigil Mode), [`SigilModule/border.jsonc`](https://github.com/klein-3000/fastfetch/blob/main/SigilModule/border.jsonc) (Border Style), [`ascii.jsonc`](https://github.com/klein-3000/fastfetch/blob/main/ascii.jsonc) (ASCII Config), [`SigilModule/simple.jsonc`](https://github.com/klein-3000/fastfetch/blob/main/SigilModule/simple.jsonc) (Simple Style)
