/* Smoked Glass 2: Elijah's system for internal apps (picked 2026-11-08, round 3 system 02; version 2 on 2026-11-11).
   Source of truth: C:/BB Projects/design-language/smoked-glass/. Rules: DESIGN.md next to this file.
   Copies live in the apps that use it (consumers.json lists them). Change here first, run `node check.mjs`, then copy.

   This file can be copied as it is: it has no @import (load Geist with a <link>, see DESIGN.md "Using it") and
   every blur goes through var(--sg-backdrop), which survives bb's plugin CSS build.

   Token rule: a token's value is a literal, never another var(--sg-*). An alias is resolved on the element that
   declares it, so it would keep the dark value under .sg-light. Compose tokens in rules, not in other tokens. */
