Change poster on title to it's own unique font

Hi! I am trying to change the title of the poster images, the css code I am using is changing the font, but it isn't the correct font that should be populating, any ideas?

url https://pear-lavender-94a9.squarespace.com/youre-getting-old-v2

code being used right now:

@font-face {
    font-family: 'Senilita';
       src: url('FontURLhttps://static1.squarespace.com/static/5d1bbd2535c22a0001cd7748/t/648b30001abcdb3a4644b759/1686843392439/Senilita.otf');
  }

#block-yui_3_17_2_1_1685547711558_16069 .image-title * {
   font-family: 'Senilita';
}
#block-df015e4daf91747a7012 .image-title * {
   font-family: 'Senilita';
}

Remove the text "FontURL" from your code
