html-tidy takes care of some post-processing, rendering other
substitutions obsolete. Remove the obsolete regex substitutions.
Now that we did that, the remaining substitutions can be done with
vanilla POSIX or POSIX-Extended regular expressions. Replace sd with
sed, and group the substitutions together into one invocation instead of
multiple invocations piped together. This change speeds up
post-processing to be almost as fast as the initial build step.
Left bc I quit trying to make a good first-party iframe alternative
that conformed to my site design standards while also imparting the
message of GEORGE as intended.
Whether I join or leave, GEORGE lives on. Whether GEORGE of the JUNGLE
or CURIOUS GEORGE, GEORGE is coming and GEORGE will be known to all as
as the one true GEORGE.
