/* ============================================================
 * NextGen MIS — Icon modernisation (Font Awesome 4 → Phosphor)
 * ------------------------------------------------------------
 * Templates keep their `fa fa-*` classes untouched. We remap the
 * ~32 icons actually used to Phosphor (friendly, MIT, SVG) via
 * CSS mask-image. Each icon:
 *   - inherits text colour (background-color: currentColor)
 *   - scales with font-size (1em box)
 *   - is a crisp SVG, not a font glyph
 *
 * Phosphor SVGs live in /img/icons/phosphor/ (regular weight).
 * Any fa-* class NOT listed here still renders via the FA font,
 * so this swap is graceful — no missing icons.
 *
 * To add an icon later: download the Phosphor SVG into that
 * folder, add the selector to the shared block, add a --ph line.
 * ============================================================ */
