/**
 * src/css/pages/dobo.css — dedicated DoBo page (AI-Studio/Gemini layout).
 * Owns dobo.html only. Reuses component classes from dobo2-dock.css
 * (bubbles, traces, cards, composer) + tokens from design-system.css.
 *
 * RK review (2026-08-01): dobo.html now uses the STANDARD app shell (the
 * same left sidebar-nav + topbar as index.html — see index.html/styles.css/
 * design-system.css for those). This file therefore only owns the CONTENT
 * area rendered inside <div class="main-content">: a flex row (.dobo-layout)
 * with the workspace (hero → thread → composer) on the left and the session
 * rail as a fixed-width column on the RIGHT (border-left, not border-right,
 * per RK: "keep the main navbar of the app same, give another nav bar
 * (sessions) on the right"). On <=900px the rail becomes a right-side
 * off-canvas drawer with a scrim, toggled from the header's
 * #doboRailToggle button (see dobo.html / dobo-page.js).
