   LEAK CHECK — /leak-check · /es/leak-check
   The instrument that prints the bill nobody sends you.

   One family (.lk-), on the shared canvas from design-dna.css. The receipt
   geometry is lifted from .rv-ledger in css/rv-pricing.css so money keeps
   looking like a printed bill and never like a pricing card, which is the
   pattern that has already been rejected here.

   Amber is what leaks (--rg-cycle-ink). Emerald is what is closed
   (--rg-evidence-ink) and is never used on a leaking line.
   Mobile first: this gets answered on a phone, with one thumb.
