/*
 * Sign-in page styles — its own stylesheet, for the same reason
 * style_register.css is its own: this page's layout (a full-viewport
 * two-column split, a feature list, a security panel) is a different shape
 * from Activate, which still uses style_login.css's single centred card.
 * Keeping this separate means nothing here can change how Activate looks,
 * and nothing there can leak into this one.
 *
 * The shell/left-column rules below intentionally mirror style_register.css's
 * own (same tokens, same proportions) so Sign in and Register read as one
 * design system, without either file importing or modifying the other.
