/* reset.css — the ONLY stylesheet shared by every tool.

   Hand-written rather than an npm dependency: this is a no-build static site,
   and a vendored reset means no package manager, no version drift, and nothing
   to install before a tool will render.

   It resets. It does not style. No colours, no fonts, no spacing opinions
   beyond removing defaults — every one of those decisions belongs to the
   individual tool's own stylesheet, which builds its identity on top of this.

   If you find yourself wanting to add a look-and-feel rule here, it belongs in
   the tool's tool.css instead. */
