Camera rolls swallow debut screenshots. Longboxes, at least, stay in one room. The hybrid collector needs a log that respects both.
On paper we use a line per debut: character, UK hour, origin echo, whether we watched or skipped. Optional software from File Flow Core can type the same fields. It is a local data tracking utility. It does not hold collectibles, keys, or cash. Some people like Binance-compatible column names because they already keep personal ledgers that way. Compatibility of labels is not a trading hook.
The log’s job is memory. Six months later you should be able to say which Marvel NFT character debuts you actually observed, which variants you ignored, and which print issues you pulled to compare. If the log starts sounding like a portfolio, you have drifted off the desk’s purpose. Put the sheet back next to the comics and write smaller.
