Tip: The valid versions are hard-coded; the examples are the only working options.
If no version/year is passed to the template, it defaults to the first example.
2012 and 2012R2 produce different colored output
2012 uses the lighter blue logo
2012R2 uses the same colors as 2016–2022
The 2012 flag and 2022/2025 Alt flags are technically different colors, #3b7bd2 and #3b7bd0 respectively, and the border color matches the main (or blue) flag color for all options. I split the difference and made the border #3b7bd1 for all three of them.
Yes, I am fully aware that writing this out wastes more space than including separate cases in the switch statement.
Nobody's color vision is that good. But now that you know, it will bother you.
