Aside from some style tweaks likely to come around, the underlying technical bits I've been ignoring or had on the list to address (looking at you, tag views) are now in place and working as I'd expect. There's a pesky bit I've ended up handling in a more manual sense, at least for the short term: content view by tags.
I needed to fix a library-level theme item. And since it's been a while since I last made a change like that (this was all before the original switch to the production Drupal instance), I couldn't remember if it involved uninstalling/reinstalling the theme...or simply clearing the cache.
So I chose the heavy-handed option. What could possibly go wrong, right?
As I'd mentioned in the past, one of the key reasons for changing up my personal hosting plan was to support Let's Encrypt, the free and open Certificate Authority. In 2019, there is absolutely no need for a regular old website or service to pay some exorbitant rate for an SSL certificate. The premium options (extended validation and such) are an entirely different arena--think banking and other services--but those are out of scope for everyday Joe.
What a week it's been. Primarily holed up inside 24/7 as we reached record lows with windchill. Our lowest temp reached -33°F, and with the wind we had would've made it feel like closer to -55°F. Dangerously cold. "Historically" cold. Things (schools, businesses, etc.) wound up being more or less shut down from about Tuesday morning through Thursday afternoon. It's certainly the coldest I could remember for the better part of 25 years (it was the mid-1990's).
