Overview

Package ui provides terminal styling for gastown CLI output. Uses the Ayu color theme with adaptive light/dark mode support. Design philosophy: semantic colors that communicate meaning at a glance, minimal visual noise, and consistent rendering across all commands.

Status icons - consistent semantic indicators Design: small Unicode symbols, NOT emoji-style icons for visual consistency

View Source 
const (
	StatusIconOpen       = "○" // available to work (hollow circle)
	StatusIconInProgress = "◐" // active work (half-filled)
	StatusIconBlocked    = "●" // needs attention (filled circle)
	StatusIconClosed     = "✓" // completed (checkmark)
	StatusIconDeferred   = "❄" // scheduled for later (snowflake)
	StatusIconPinned     = "📌" // elevated priority
)

Issue status icons - used consistently across all commands Design principle: icons > text labels for scannability

View Source 
const (
	TreeChild  = "⎿ "  // child indicator
	TreeLast   = "└─ " // last child / detail line
	TreeIndent = "  "  // 2-space indent per level
)

Tree characters for hierarchical display

View Source 
const (
	SeparatorLight = "" /* 126-byte string literal not displayed */
	SeparatorHeavy = "" /* 126-byte string literal not displayed */
)

Separators - 42 characters wide
