/*
 * Dynamitey documentation theme.
 *
 * The project's own identity, deliberately not any company's. This is a
 * community continuation of an Apache-2.0 library whose copyright is retained
 * upstream, so the site should look like it belongs to the project rather than
 * to a maintainer.
 *
 * Almost everything here is expressed through Bootstrap 5 custom properties
 * rather than by overriding DocFX's own selectors. Those variables are the
 * template's supported surface; its class names are not, and a DocFX upgrade
 * that reshuffles them would silently break a stylesheet written against them.
 *
 * Palette: a slate ground with a single ignition-amber accent. One accent used
 * consistently reads as deliberate; three read as decoration.
