side devlog 3: less clutter + a manager page

the page had way too much going on fr. cut the face readouts, the demo stepper, extra stats and the giant verify box.

• headline rises in word by word, the face boots up with its eyes opening, sections fade in once, and the nav has a little pill that slides around. all of it switches off if u have reduced motion on
• made a site manager (npm run admin). edit any text, pick which commit stable points at, update the roadmap, all next to a live preview. saves as u type
• drag an installer onto a platform and it gets hashed on upload, so the page shows the real sha-256. no more copy pasting hashes by hand
• it only runs on localhost and never ships in the build, so nobody’s editing my site but me. hehe nice try.

Now that i think about it. i think i did way too much unneccessary stuff.
