Onsen Mirador
A geothermal bathhouse of six pools cut into basalt, open in three-hour sessions with a maximum of forty bathers. There are no treatments, no music and no phones past the lockers.
Steam, dark water, a serif that whispers. Best mood on the sheet.

The brief the agent was handed
What it was asked for.
Audience
City workers booking a three-hour reset, not a full spa day
The pitch
Onsen Mirador is a geothermal bathhouse with a strict silent-bathing policy, sold in three-hour sessions with no treatments and no phones. The page is a split-screen scroller pairing each pool with the exact temperature and what it is for.
Sections it decided on
- Split hero: steam over water and the silence rule
- The six pools, each with temperature and purpose
- The circuit: how to move through it in three hours
- Silence, nudity and phone policy, stated plainly
- What we do not have: no treatments, no bar, no music
- Session times and how few people are in at once
- Accessibility, and what we can adapt
- Reserve a session
The run
Fifty of these. About one developer day.
Same toolchain, fifty different briefs, no templates. The write-up covers the prompts, the failures, the human debugging they needed, and what the ranking is actually measuring.
