/* Signal Dark — tools screen styles (P4, epic #1525)
 *
 * Lifted VERBATIM from tests/parity/mockups/tools.html <style>.
 * Shared atoms (.frame, .sb, .cut, .mono, .bdg, .btn, .sect, .statgrid,
 * .trow, .fnav, tokens) live in signal-dark.css and are NOT duplicated here.
 * This file owns only the tools-specific modules.
 *
 * Token divergence note: the mockup used slightly different light values
 * (--bg:#f2f0ea, --card:#fbfaf6, --mut2:#9b9ea4) — the ported screen inherits
 * signal-dark.css tokens which are close (--bg:#f4f2ee, --card:#ffffff).
 * The diff is sub-pixel on parity shots; flagged here for awareness.
