How do you anti-alias your headlines/use Din even though I don’t have it installed?

IFR or Inman Flash Replacement. You can find my original writings about the technique here but going forward I strongly recommend using the refined sIFR or scalable Inman Flash Replacement. Mike Davidson and Mark Wubben have really simplified its implementation, ironed out a number of accessibility issues and made it available (thoroughly documented) at MikeIndustries.com.
