   Filter bar: a real GET form so filtering is server-side and zero-JS. Config:
     rows: Control[][]            rows of controls, laid out left→right
     pills, clearHref, label, action, applyLabel
-  Control.type ∈ search | segmented | select | chips | daterange | spacer.

   The form is a GET, which replaces the whole query string — so the visitor's chosen language rides
   along as a hidden input, and every href here (pills, clear) is run through localeHref.
