/* Victory Christian School — Parent App
   Thesis: Victory's torch on royal blue, worn like a letterman jacket — proud, calm, built for a tired parent's thumb.
   School colors are blue and white. Signature: the royal header with the white torch and two white "jersey stripes"
   along its base. Everything else stays quiet. */
