+# Hack the Planet
+
+A cinematic hacker-movie simulator by [Kastro Labs](https://kastro.is). Live at [htp.kastro.is](https://htp.kastro.is).
+
+**Mash any keys. Become a movie hacker.** Pick a fictional target, type literally anything while convincing code pours out of your fingertips, survive the firewall counterattack, crack the password one glowing character at a time, siphon the files, and walk away with a mission report worth screenshotting.
+
+It is 100% fiction. Nothing is scanned, contacted, or harmed. Every target is invented, every exploit is theatre, and the only thing under attack is realism.
+
+## How it plays
+
+1. **Boot** — BIOS theatrics. The reality driver is intentionally NOT FOUND.
+2. **Jack in** — pick a two-word hacker handle with zero humility (or randomize one).
+3. **Pick a target** — THE GIBSON, an orbital disco satellite, an evil bank's bonus pool, or the Global Genius Database.
+4. **The run** — type *anything*; any keys work. Fill the ACCESS meter, out-type the TRACE during the firewall counterattack (go idle and you *will* get traced), then keep mashing through the exfil.
+5. **Debrief** — keystroke stats, trace peak, an operator rating from SCRIPT KIDDIE to ZERO COOL CERTIFIED, and a copyable mission report.
+
+Extras: `ESC` summons a boss-screen spreadsheet, sound is synth-only and off by default, the world map decodes real TopoJSON with zero libraries, and the whole thing works on a phone via the big MASH button.
+
+## Running it
+
+```bash
+go run .          # http://localhost:8080
+PORT=3001 go run . # any port you like
+```
+
+One Go binary, all assets embedded, no runtime dependencies, no database, no analytics, no network calls except serving itself.
+
+## Stack
+
+- **Server:** Go standard library only (`embed` + `net/http`), ~100 lines.
+- **Frontend:** vanilla ES modules, two canvases, CSS. No frameworks, no build step.
+- **Audio:** WebAudio oscillators, generated on the fly.
+
+## Checks
+
+```bash
+gofmt -l .
+go test ./...
+go vet ./...
+go build ./...
+```
