# 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 -e "${GREEN}${BOLD}$1${NC}"
}


# Individual actions/steps - inline result format
log_action() {
    echo -n "  $1... "
}

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

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

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

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

# For errors, show full output prominently (not grayed)
log_error_output() {
    echo "$1"
}

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

# Detailed output (errors, etc.)
log_detail() {
