NIGHTINGALE EDUCATIONAL TRUST — portfolio site + admin panel
Design: "dawn chorus" — deep dusk teal fading to sunrise gold,
a nightingale drawn across a music-staff branch as the
signature motif (ties to the school's real anthem "Nightingale
ke Sitare"). Trust objectives use a numbered list because a
trust deed's objectives genuinely are an enumerated clause.

aboutHeading: "Our story",
aboutBody:
"Nightingale Educational Trust was formed to give Uluberia a school that took English fluency and computer literacy seriously from the very first classroom. What began as a single nursery on Rajkhola Road has grown into a small community of students, teachers, and families who return every year for the annual function, the sports season, and the songs the children write themselves. The trust exists to keep that growing — responsibly, and for more children each year.",
objectives: [
"To establish, run, and manage educational institutions imparting quality education from pre-primary to secondary level.",
"To promote English-medium and computer-based learning accessible to children of Uluberia and the surrounding areas.",
"To provide scholarships, study materials, and financial assistance to meritorious and underprivileged students.",
"To organise co-curricular, cultural, and sports activities for the holistic development of every child.",
"To conduct teacher-training programmes and community welfare initiatives in the field of education.",
