/*
 * Talking Time MentorPlannerCard styles — tabbed planner with
 * Timetable, Expenses, Calendar, Checklist.
 *
 * All selectors are scoped under ``.tt-area`` so the LINGO side is
 * untouched (Req 5.5). The card provides its own tab bar styling
 * rather than reusing global button classes to avoid specificity
 * conflicts with the LINGO palette.
 *
 * Requirement 32.1, 32.2, 32.3, 32.4, 32.5, 32.6, 32.7
