/* CrispSign Lobby Panel Builder — layout stylesheet.
 *
 * Header + drawer + account cluster come from styles.css + site-chrome.css
 * + builder-v2.css (all loaded before this file). We only layer product-
 * specific layout on top and reuse the site design tokens.
 *
 * MODELED ON yard-sign.css: class names below are a mechanical .ys- -> .lp-
 * rename of that file's shell/rail/stepper/upload/review/footer rules (same
 * visual system, same tokens), with panel-specific additions appended at
 * the bottom (material grid, seg/seg-btn control, standoff dot layer, and a
 * CSS-only wall backdrop since no photoreal lobby-wall asset exists yet —
 * see RESULT-lobby-panel.md open risks).
