/*
 * Design tokens. Nothing else.
 *
 * No layout, no components, no face declarations, no font loading. Those arrive with the
 * DESIGN_SPEC layout session; this file exists so that when they do, there is somewhere
 * for a value to come from other than a literal.
 *
 * THIS IS THE ONLY FILE IN THE REPOSITORY THAT MAY CONTAIN A HEX LITERAL.
 * CLAUDE.md §7 and DESIGN_SPEC §4.1: not in a template, not in an inline style, not in an
 * SVG attribute, not in a comment showing what a token resolves to. ADR-004 §8 rule 6
 * makes it a grep over src/render/**, and src/render/__tests__/boundaries.test.ts runs it.
 *
 * Logical properties only, everywhere downstream: margin-inline-start and padding-inline-end,
 * never their physical counterparts. CLAUDE.md §11, and this file must not name them even in
 * prose, because the check that enforces it is a grep over the whole file.
