/* Design Plan:
 * 1. Subject: Pusat Tuisyen Cemerlang, an elite, professional academic coaching & learning centre for primary and secondary students.
 * 2. Visual elements & materials: Deep executive navy slate (#0f172a / #1e293b), crisp gallery white (#ffffff), refined warm parchment background (#f8fafc), prestigious emerald teal accent (#0d9488), muted slate typography (#475569), subtle silver hairpins (#e2e8f0).
 * 3. Category contrast: Unprofessional tuition sites often look cluttered, childish, with loud cartoon elements or haphazard colours. This site projects high-calibre academic rigor, institution-grade credibility, clear structured tables, and a calm, confident enrolment experience.
 * 4. The Idea: On this site, the atmosphere of an established private academic academy becomes a structured, high-clarity enrolment portal with real-time seat tracking and verified KPM syllabus alignment.
 * 5. One bold element: The executive live seat reservation matrix that pairs real-time capacity monitoring with instant quota locking.
