| Variation of https://backbonenotbad.hyperclay.com/ using just the "platform" for funsies. | |
| So no external resource. No React. No Backbone. No Tailwind. | |
| Admittedly cutting corners quite brutally. | |
| Replicates most flaws of the original(s): | |
| - Accessibility disaster: no labels, no aria-live regions, no clear indication what is going on. | |
| -- (Added a feeble attempt with CSS content "alt"s, but I doubt any current SR would catch them.) | |
| - Resilience disaster: no features detection, no graceful degradation. | |
| - Will break in any fairly outdated user agent. Will not work without JS (just like the original, but now even worse, rendering non-functional UI. (There should be server-side fallback anyway.) |
