One nit regarding website, toggling dark mode causes a video change that has some ugly flashing, I think you could improve this by recording the video without dropshadow and adding the shadow with CSS.
Thanks for your suggestion, I'll consider it. But what do you mean by ugly flashing? Is it the instant background change that turn you off?
Also, there's a problem with responsive text reflow on your personal site, I've only noticed because I'm using a tiling wm.
I've made videos to showcase
I think for the first issue, with the flashing, it seems to flash to you, but it's just the theme being changed to light, isn't it? Or you are specifically only talking about the way the video container doesn't fit the rest of the page while it's loading?
Regarding the second issue, good catch! I'll fix that. Thanks!
I'll try to see what I can do about it to make the transition easier on the eyes, so thanks for the feedback.
