// Render-blocking branding primer (#38). Loaded as a synchronous same-origin
// <script> right after the sidebar logo, so it runs DURING parse, before first
// paint — applying the current workspace's CACHED white-label so the page paints
// branded instead of flashing the "ScreenTinker" default. branding.js then
// refreshes it from the server and re-writes the cache. Plain script (not a
// module) so it's not deferred; keyed by workspace so a switch shows the right
// brand (or the neutral default for a workspace we haven't cached yet).
