/* One stylesheet, implementing docs/DESIGN.md ("Fils").
 *
 * The application is dense, internal, and read on a desktop by people who use
 * it all day, so it is laid out for scanning tables rather than for a first
 * impression. Every rule below traces to a numbered section of that document;
 * the section is named where the reason is not obvious from the code.
 *
 * Two mechanical rules govern this file and are enforced by
 * tests/test_design_tokens.py:
 *
 *   - No colour is defined only under dark. The full light set lives on
 *     :root and dark redefines the same names (DESIGN.md 2.4).
 *   - No physical left/right property. Logical properties only, so turning
 *     Arabic on is a direction flip and not a rewrite (13).
 */

/* ── faces ────────────────────────────────────────────────────────────────
 * Self-hosted, committed, never fetched. The host may have no egress and
 * runs a strict CSP, which is the same reason jQuery is vendored (15).
 *
 * Only the Latin1 subset of each face ships. Arabic (13) is a third file
 * added when the locale is switched on, not a redesign.
