  /* Each accordion instance MUST be scoped by its checkbox's own #id on
     both sides of the selector, not a class shared between sections. Two
     bugs came from that sharing: (1) a generic
     ".collapsible-checkbox:not(:checked) ~ .collapsible-content" matches
     as soon as ANY earlier checkbox on the page is unchecked, regardless
     of which panel it belongs to; (2) even after scoping the checkbox
     side by #id, .filter-bar also carried the generic ".collapsible-
     content" class so #cities-toggle's own rule still matched it and hid
     it whenever the (unrelated, untouched) city panel was collapsed. Fix
     for both: each panel gets its own unique content class (.filter-bar
     is already unique on its own — it doesn't need "collapsible-content"
     too) and each rule pairs one #checkbox-id with that one unique class,
     nothing shared. Add one more such pair for every future collapsible
     section — copy-paste, don't genericize. */
