Don’t look too far into android if the browser having a bunch of compatibility exceptions baked in makes you squeamish.

May I interest you in lynx?

Pretty sure it’s always been like this.

The web is a mess. If you do anything on it on any combination of software and hardware and expect security or functionality you’re barking up the wrong tree.

There isn’t anything that meets your criteria.

Optical suffers from separation, hard drives break down, ssds lose their charge, tape is fantastic but has a high cost of entry.

There’s a lot of replies here, but if I were you I’d get last generation or two’s lto machine from some surplus auction and use that.

People hate being told to use magnetic tape, but it’s very reliable, long lived, pretty cost effective once you have a machine and surprisingly repairable.

What few replies are talking about is the storage conditions. If your archive can be relatively small and disconnected then you can easily meet some easy requirements for long term storage like temperature and humidity stability with a cardboard box, styrofoam cut to shape and desiccant packs (remember to rotate these!). An antifungal/antimicrobial agent on some level would be good too.
