π-cross: Site accessibility and mobile-friendly design checks

[Brycey92]

Since font sizes and things have been changed between https://picross.hdyar.com and https://swadge.com/picross/, we need to double-check that the new site (the swadge.com link) is still accessible to those with reduced vision, and that it works well on mobile.

We need alt text on the images describing what's actually there, so the site could still be used if images don't load or someone is having the site narrated

also we got this super cool thing https://wave.webaim.org/report#/https://swadge.com/picross

Accessibility isn't a nice-to-have, it should be a requirement. Updated labels accordingly

[AEFeinstein]

Making the instructions accessible for the visually impaired is incredibly noble, but the game itself is not accessible in that way, so while there is value, there may not be as much as you think.

Damn it 😂
