yep, got it 👍

Ah I see! Haha the funny thing is that it's Gen X and early millennials that played these games. Atari and pong are more boomer era. I'm insulted! Hahahaha 🤣

Bow bow chicka bow bow. <the lights dim>

win-shift-s and ctrl-v into imgur like https://imgur.com/a/faLoO68 (or any other place one can dump pictures onto – say Discord if one never deletes it there, or any screenshot application with built in uploading) is a sort of quick process.
before that it's just a click on 'gift' for each game, and afterwards a click out of the modal so it closes again.

I suppose it takes two minutes, or three at worst? That's at least less time than it takes to try to understand the actual locks on SteamDB, or run a bundle split on Group Buys, or decide on the wording of a forum post.

(Is a manually kept account activation log anything that https://lab.xpaw.me/license-parser.html can't do? I always figured I'd use that if I really wanted to take a peek into what I own.)

I always thought Humble gift link notifications were notoriously untrustworthy

They're untrustworthy in the sense that the countries list doesn't reflect the region locks that YOUR key has. Keys that can be activated worldwide also show a huge list of countries, and the buyers who receive ROW keys are tempted to think that their key is region locked because of that big list.
But in fact, that list should be read as "these countries DO receive a region lock key, or no game at all". If taken with this meaning in mind, then they are very reliable. Sure, there are also errors from time to time, but in most of the cases they are very accurate.

often showing information that does not correspond with any known region locks or packages on SteamDB

It happens quite often that the region locked package is not indexed on SteamDB, but that's usually because these packages are newly generated by publishers likely for that specific bundle. As you probably already know, Valve restricted the discovery of non-store packages a few years ago, so without a token from someone who actually owns the package, SteamDB is unable to index it.

Fanatical is a completely different story though. It's a mess and extremely unreliable.
With Fanatical you don't have the concept of "these countries DO receive a region lock key, or no game at all". For some Fanatical bundles, there's some info in the API about the region locks, but this is shown even if no one actually receives a region locked package. It's probably some sort of info that they have indexed about what kind of packages could exist, but it doesn't reflect the packages they decide to deliver in a certain bundle.
The API info is also incomplete, for example they show a region lock for Russia-only sometimes, when the package is actually for the whole RU/CIS - unknown if that means that for Russia specifically they give the RU/CIS package, and for the rest of RU/CIS countries they just give ROW keys. This never happens with Humble Bundle: if a RU/CIS package exists and they decide to deliver it in a bundle, then it's consistently allocated to all RU/CIS countries and not only to some of them, selectively chosen.

early access games are a gamble. it is not known how long they will remain in this stage and in general they are full of bugs
