/* =============================================================================
   BlueSilica app theme  -  the Infralytix "Iron + Amber Copper" theme, for every BlueSilica app.

   Source of the tokens: tb-infralytix-repo/branding/infralytix/themes/infralytix-theme.css (the `--ix-*` values in the light block
   are copied from it). Only the THEME is shared. Logos are not: Infralytix keeps its logo, BlueSilica AI keeps its own.
   Fonts are self-hosted (fonts/), so on-premises systems without internet render the same.

   Use:  <link rel="stylesheet" href="theme/theme.css">   then your page CSS (layout only).  See README.md.
   Light is the default. <html data-theme="dark"> is dark; <html data-theme="system"> follows the device. theme.js sets it and
   draws the Light / Dark / System switch (place <span data-theme-switch></span>).
