/* shell.css - AiAD STUDIO IN THE SHOWROOM'S LOOK (11 Oct 2026, his go of 02:50: "THIS IS THE CHOSEN LOOK OF AIAD STUDIO -
 * THE SOFTWARE AND THE SHOWROOM", "continue with the same design system, make all the icons and the tools ... match this style").
 *
 * A MOUNT, NOT A REWRITE: the Studio's own elements (header, #tabs, #ribbon, .grp, .tool, #tree, #part, #term, #log, #prompt, #hud,
 * #selbar) are dressed in the kit's values (ak-tokens.css, kit.css); shell.js adds what the page lacks (the sprite's icons, the
 * groups' names, the doors, the terminal's header, the view cube). Every hook app.js and the acceptance set use stays as it was:
 * #tabs button[data-tab] with .on, #ribbon .tool[data-tool], the ids. Loaded after the page's own <style>, so equal weight wins here.
 * Values only from the kit: one face (mono), its sizes, its colours by job (ice = chosen, gold = the mark, an accent, a selection). */
