Welcome! The first page looks pretty decent and it's good you've done that much planning ahead of time. Just don't get discouraged if it all turns out to be a bit more work than expected, even a medium length CYOA can take a certain amount of dedication once all those alternate paths start adding up.
You don't have to worry about indenting paragraphs, that's actually a bit annoying to read on a screen. (Though it looks like you drop that after the first page anyhow...)
Once quick note on dialogue before you get any further:
“We are going tonight!” she declares. “I already have it worked out. I will sneak out around-”. // This is correct.
“A birthday is a special night indeed. Follow me to the back if you would,” the woman smiles reassuringly and stands to return to the back room. // The dialogue in this case should end with a period and 'The woman' should be capitalized because we're dealing with a separate sentence now, not just 'the woman says' or whatever appended to the dialogue part.
Mistakes involving dialogue punctuation are super super common and I see them all the time even with the better authors around here, so it's a good thing to straighten out early. I usually send people to the
Grammarly Handbook, but there are a lot of sites out there that give examples and explain it all better than I could, such as
this one. (Which contains a lot of good general writing advice as well.)
