/* ============================================================
 * Boardly Chrome — TopBar (+ SubBar-Stub Sprint 8) — Story 0064a / ADR-0030
 *
 * Reverse-engineered aus .project/design/styles.css Zeilen 127-262.
 * Sprint-7-MVP: TopBar inklusive Brand-Dot, Brand-Fam, Top-Sep, Top-Btns,
 * Avatar-Stack. SubBar (Workspace-Switch + View-Tabs + FilterChip + AiPill)
 * ist Sprint-8-Stretch (Story 0064b) — Selektoren bleiben hier vorbereitet,
 * werden aber Sprint 7 nicht gerendert.
 *
 * Reihenfolge im HTML (App.razor): tokens.css -> shell.css -> chrome.css
 * -> board.css -> card.css -> pages.css.
 *
 * shell.css definiert die Topbar-Box-Klassen (.topbar, .brand, .brand-dot,
 * .brand-fam, .top-sep) bereits Sprint-1-konform; chrome.css ergaenzt nur
 * die Boardly.html-spezifischen Erweiterungen (.top-btn, .avatar-stack,
 * .avatar) und ueberschreibt nichts. Wenn Klassen kollidieren, gewinnt die
 * spaeter geladene Definition (chrome.css) per CSS-Cascade — Boardly.html-
 * Werte sind die kanonischen.
