inverse logic for 'get everything' agrument (currently, only external use)
search specific forms vs. all document when performing cleanup
more explicit types, allow imports
minimal type info for internal and some external funcs
fix Ago updates depending on uptime, use onmessage
html/src/types/* useless (at least without tsc actually running)
remove leftover manual template merge, idForContainer() should just use template-id data key
group add event now checks that instead, raising alert when number is greater than max
ref. #2610
* migrate to esbuild from terser, since now js source needs bundling
* (temporary?) hijack inline-source object handling to inline html files
* get rid of legacy removeIf comments in source in favour of explicit
removal either through bundling tree-shaking and / or manual module-*
class element removal w/ jsdom
* get rid of multi-layered custom checkboxes in favour of
`appearance: none` directly styling the `input` elem
also removes scripting part that was supposed to adjust for=... labels
* update to html-minifier-terser, up-to-date html-minifier fork
* update to iro.js 5.5.x, using npm to manage dependencies
* build script can now update resulting html output
(called after bundling stage, before minification)
