/* CANONICAL LOCKUP — DESIGN-GUIDE §8, re-derived 2026-08-08.
   Ratios are measured on VISIBLE INK against the tight 1:1 asset:
   mark box = 1.77 x cap · gap = 1.06 x cap · mark bottom sits 0.38 x cap
   BELOW the wordmark baseline. Outfit 600 cap height = 0.703em of set size.
   Derivation at 18px: cap = 18 x 0.703 = 12.654px -> mark 22.4px,
   gap 13.41px, drop 4.81px. If the set size changes, recompute all three
   from the ratios — never eyeball. (The previous 1.39/0.46/0.27 were measured
   on the PADDED asset box, which rendered the mark at only 1.06 x cap.) */

/* §9 IDENTITY CHROME — THE canonical control (DESIGN-GUIDE §9). One definition;

   their FIRST initial only (§9 amendment 2026-08-06 — never two letters). */

/* ── Theme toggle ─────────────────────────────────────────────────────────
   THE canonical control, here because lockup.css is the one header stylesheet
   every consumer already loads: public/index.html, public/404.html,
   src/routes/legal.js, shared/partials/budtello-header.html and
   src/views/navShell.js (which inlines this file).

   It lives here because it did NOT live anywhere navShell could see it. The
   phase-2 swap (ADR-0342) copied the toggle MARKUP into the authed header but
   not these rules, so on /app all three glyphs painted at once — sun, moon and
   the system half-circle side by side inside one button, read as "two toggles".
   The button ships three <svg>s and exactly one is revealed by preference;

   Icon shown reflects the PREFERENCE: no stored preference = the system glyph,
   because the default on every surface is the OS scheme. */
