Adding a wave pattern with .svg Dawn/origin Screenshots attached

Hey! I want to add a wave pattern to the website and at the moment I just included the pattern in the images but thats not working due to quality being lossed based on screensize and it just being inconsistent etc, is there a way i can add a custom liquid between each section with the .svg overlapping into the section above or below to create this same effect but in a better way. maybe there is another way someone knows to achieve this.

    transform: translateY(-102px);
    margin-bottom: -102px;
    --mask: radial-gradient(96.55px at 50% 136.5px, #000 99%, #0000 101%) calc(50% - 140px) 0 / 280px 100%, radial-gradient(96.55px at 50% -66.5px, #0000 99%, #000 101%) 50% 70px / 280px 100% repeat-x;
    -webkit-mask: var(--mask);
    padding-top: 100px;
