/* Shared styles for the public /tools/ calculators. Loaded alongside style.css
   on every tool page. Keeps each tool page's own <style> block small (page-
   specific layout only) instead of repeating this on all four pages. */

/* Several rules below (e.g. .tool-copy-btn's display:inline-flex) apply to
   elements that also carry the HTML `hidden` attribute at times. Author
   CSS with a display value beats the UA's built-in `[hidden]{display:none}`
   rule under normal cascade/specificity rules, so any such element renders
   visible even while `hidden` (found in review: rate-calculator's empty
   #area-dims-row happened to hide this since it has no visible content
   when shown by mistake; lawn-size-calculator's Finish/Cancel buttons do
   not, and were visibly wrong on load). One rule here fixes it everywhere
   `[hidden]` is used across the tool pages, rather than patching each
   affected element's own display rule individually. */
