# Design principles:
# 1. Minimal visual noise - use color sparingly for emphasis
# 2. Clear hierarchy - different levels of information have different treatments  
# 3. Consistent spacing - clean vertical rhythm
# 4. Accessible - readable without colors

# Main header for script/tool name
log_title() {
    echo ""
    echo -e "${BOLD}$1${NC}"
    echo ""
}

# Section headers for major phases
log_section() {
    echo -e "${BOLD}${BLUE}$1${NC}"
}

# Individual actions/steps
log_action() {
    echo -e "  $1..."
}

# Results - success/failure/info
log_ok() {
    echo -e "  ${GREEN}✓${NC} $1"
}

log_fail() {
    echo -e "  ${RED}✗${NC} $1"
}

log_warn() {
    echo -e "  ${YELLOW}!${NC} $1"
}

log_skip() {
    echo -e "  ${GRAY}-${NC} $1"
}

# Final summary
log_summary() {
    echo ""
    echo -e "${BOLD}$1${NC}"

# Detailed output (errors, etc.)
