   MiLabFQ — Identidad visual
   Bitácora digital de Biofarmacia · Facultad de Química, UNAM

   La identidad parte de la libreta de laboratorio encuadernada:
   - el azul institucional es la cubierta;
   - el filete dorado es la greca que separa cubierta y hoja;
   - la hoja blanca es la superficie de trabajo;
   - el escudo FQ es el único elemento con movimiento propio.

   Reglas de la casa:
   - el filete dorado marca jerarquía, no decora;
   - una sola familia de display (Sora) y una de texto (Source Sans 3);
   - sin sombras difusas: borde fino + filete;
   - movimiento solo cuando responde a una acción;
   - líneas de texto por debajo de 75 caracteres.
