/**
 * taoCustom — IHSO Reokpe Branding Theme
 *
 * Targets IHS Schools CBT's real DOM selectors (verified against
 * tao/views/templates/layout.tpl and taoBackOffice theming conventions)
 * while layering on CSS custom-property fallbacks for forward compatibility.
 *
 * Colour palette derived from the IHSO Reokpe badge / logo identity:
 *   Primary   #1a3a6b  (Deep navy — dominant logo fill)
 *   Accent    #c8922a  (Gold — logo highlights / CTAs)
 *   Light     #f0f4fa  (Off-white page background)
 *   Text dark #1a1a2e  (Headings / body copy)

   • Make the anchor a flex container so logo + text sit side-by-side
     and are vertically centred within the 65px header strip.
   • Grow the logo to 56px (badge needs room — there is whitespace in
     the PNG around the crest) while keeping the strip at 65px.
