/* NIST SP 800-88 Rev. 2, explained (/nist-800-88-rev-2/). Scoped under .tbng so nothing
   leaks into the captured Elementor shell. The same system as the law map (.tblm): night
   hero, paper body, Instrument Sans, green for "current", periwinkle as the second hue.
   Each method owns one ink everywhere it appears: Clear teal, Purge periwinkle, Destroy
   coral, cryptographic erase violet. Every section takes its own form: the live Fig. 1,
   a typed ledger, a two-step pipeline, a paper certificate, a life-cycle rail, a gate check
   with a lamp, struck-through myths, and a timeline drawn to scale. */
