/* Evenbead colour theme toggle (ADR-0099 as amended; markup from brand/theme/theme.ts, behaviour in theme.js). One icon button, no
   border, no pill, no background: a Lucide moon while the page is light (press: dark), a Lucide sun while it is dark (press: light).
   The icon takes the text colour around it (like the header and menu icons next to it; a surface may set --theme-toggle-ink) and
   --theme-toggle-size (20px by default). Hover and focus turn it the accent colour; keyboard focus also draws a ring (focus-visible
   only). The hit area is 44px square. A public page's toggle needs JS (theme.js): without it (no data-theme on <html>) it is hidden
   and the page stays light.
   .icon-link / .icon-row: the public footers' X, LinkedIn and YouTube links (brand/theme/social.ts) in one row with the toggle as
   the last item; the links look and behave exactly like the toggle. */
