/*
  Bitcoin Canon — Drawers & Sheets
  Source drawer (provenance), mobile search sheet, mobile picker sheet.
  These are the apparatus — they should feel like witness records, not utility panels.

  All three sheet surfaces use var(--c-panel), never a fixed hex. They were
  hard-coded to #101009, which is correct only in the dark themes: in Vellum the
  page supplies dark ink, so the sheet put dark text on a dark surface — the
  title and input measured 1.20:1, the close control 2.31:1. The fields inside
  sit on --c-panel-2 so they still read as inset on the panel.
