Returning to the Theme Defaults with flavor_standard()

Use flavor_standard() to override other flavors or to make defaults explicit.

# A reusable style layer for consistent plots across the project.

my_theme = (
    theme_classic() +
    theme(
        axis_title=element_text(size=13),
        axis_text=element_text(size=15),
        legend_position="left",
        axis_ticks_length=7,
        panel_grid_major=element_line(color="spring_green"),
        panel_grid_minor=element_blank()
    ) + flavor_darcula()

# To restore the theme defaults without affecting other settings, apply flavor_standard(). 
# This can be useful, for example, when exporting the plot for printing.
