Quicksand: font-display optional, not swap, to stop the text-jump on scroll
Deploy / deploy (push) Successful in 34s

Browse Source 
Confirmed via user testing that the jump was in DOM text below the
hero (headings using Quicksand), not the YES canvas (which draws in
plain Arial, unaffected). swap always paints the fallback font first
then reflows once Quicksand loads - a real layout shift if that swap
lands after the user has already scrolled past that heading, which
is exactly what was happening. optional skips the swap entirely
unless the font is already cached/ready almost immediately.

font-display: optional, not swap, on all three: swap always shows
the fallback font first then reflows to Quicksand once it loads,
which is a real layout shift if that swap lands after the page is
already scrolled past that heading - reported as "text jumps" on
real mobile Safari. optional skips the swap entirely unless the
font is already cached/ready almost immediately, trading an
occasional fallback-font render for zero shift. */
