fix: reduce reconnect backoff to 1s flat

Exponential backoff up to 300s made no sense with rotating Tor exits
where each reconnect gets a fresh IP. Single 1s delay is sufficient.

 Set server password to `mypassword` in the network settings.
 
+## Client TLS
+
+The bouncer can accept TLS-encrypted connections from IRC clients. This
+encrypts the password and all traffic between your client and the bouncer.
+
+### Setup
+
+```toml
+[bouncer]
+client_tls = true
+```
+
+On first start with `client_tls = true`, the bouncer auto-generates a
+self-signed EC P-256 certificate at `{data_dir}/bouncer.pem` (10-year validity).
+The certificate fingerprint is logged at startup.
+
+### Custom Certificate
+
+To use your own certificate (e.g. from Let's Encrypt):
+
+```toml
+[bouncer]
+client_tls = true
+client_tls_cert = "/path/to/fullchain.pem"
+client_tls_key = "/path/to/privkey.pem"
+```
+
+If the cert and key are in the same PEM file, set only `client_tls_cert`.
+
+### Client Examples
+
+**irssi:**
+```
+/connect -tls -tls_verify no -password mypassword 127.0.0.1 6667
+```
+
+**weechat:**
+```
+/server add bouncer 127.0.0.1/6667 -password=mypassword -ssl -ssl_verify=0
+/connect bouncer
+```
+
+**hexchat:**
+
+Enable "Use SSL for all the servers on this network" and accept the
+self-signed certificate.

 Stored commands: `PRIVMSG`, `NOTICE`, `TOPIC`, `KICK`, `MODE`.
 
+## PING Watchdog
+
+The bouncer sends periodic PING messages to detect stale server connections
+(socket open but no data flowing). If no data is received within the configured
+interval, a PING is sent. If the server doesn't respond within the timeout,
+the connection is dropped and a reconnect is scheduled.
+
+```toml
+[bouncer]
+ping_interval = 120   # seconds of silence before sending PING
+ping_timeout = 30     # seconds to wait for PONG after PING
+```
+
+The watchdog starts automatically when a network enters the READY state.
+Any received data (not just PONG) resets the timer.
+
+## IRCv3 server-time
+
+The bouncer requests the `server-time` IRCv3 capability on every connection.
+When enabled by the server, timestamps on incoming messages are preserved and
+forwarded to clients. When the server does not provide a timestamp, the bouncer
+injects one using the current UTC time.
+
+Backlog replay also includes timestamps from when messages were originally
+stored, so clients that support `server-time` see accurate times on replayed
+messages.
+
+No client configuration is needed -- timestamps appear automatically if the
+client supports IRCv3 message tags.
+
+## Push Notifications
+
+When no IRC clients are connected to the bouncer, highlights and private
+messages can trigger push notifications via [ntfy](https://ntfy.sh) or a
+generic webhook.
+
+### Setup
+
+```toml
+[bouncer]
+notify_url = "https://ntfy.sh/my-bouncer-topic"
+notify_on_highlight = true    # mentions of your nick in channels
+notify_on_privmsg = true      # private messages
+notify_cooldown = 60          # min seconds between notifications
+notify_proxy = false          # route notifications through SOCKS5
+```
+
+### ntfy Example
+
+```toml
+notify_url = "https://ntfy.sh/my-secret-topic"
+```
+
+Install the ntfy app on your phone and subscribe to the topic. Notifications
+include the sender, target, and message text.
+
+### Generic Webhook
+
+Any URL that does not contain `ntfy` in the hostname is treated as a generic
+webhook. The bouncer POSTs JSON:
+
+```json
+{
+  "network": "libera",
+  "sender": "user",
+  "target": "#channel",
+  "text": "hey mynick, check this out"
+}
+```
+
+### Behavior
+
+- Notifications only fire when **no clients** are attached
+- The cooldown prevents notification floods (one per `notify_cooldown` seconds)
+- When `notify_proxy = true`, notification requests are routed through the
+  configured SOCKS5 proxy

+## Background Account Farming
+
+The bouncer can automatically grow a pool of verified NickServ accounts across
+all configured networks. Primary connections stay active with SASL-authenticated
+identities while ephemeral connections register new nicks in the background.
+
+### Setup
+
+```toml
+[bouncer]
+farm_enabled = true
+farm_interval = 3600       # seconds between attempts per network
+farm_max_accounts = 10     # max verified accounts per network
+```
+
+### How It Works
+
+1. A sweep loop runs every 60 seconds (after an initial 60s stabilization delay)
+2. For each NickServ-enabled network, it checks:
+   - Is there already an active farming attempt? (skip)
+   - Has the cooldown (`farm_interval`) elapsed since the last attempt? (skip)
+   - Are there already `farm_max_accounts` verified accounts? (skip)
+3. If eligible, an ephemeral connection is spawned with a random nick
+4. The ephemeral goes through the full registration lifecycle: REGISTER, email
+   verification (or captcha), and credential storage
+5. Credentials are saved under the real network name, not the ephemeral's
+   internal `_farm_` prefix
+6. Each ephemeral has a 15-minute deadline before being terminated
+7. Ephemeral connections are invisible to IRC clients (no status broadcasts,
+   no channel joins)
+
+### Commands
+
+| Command | What it does |
+|---------|-------------|
+| `FARM` | Global overview: enabled/disabled, interval, per-network stats |
+| `FARM <network>` | Network stats + triggers an immediate registration attempt |
+| `ACCOUNTS` | List all stored accounts with verified/pending counts |
+| `ACCOUNTS <network>` | Accounts for a specific network |
+
+### Configuration Reference
+
+```toml
+[bouncer]
+farm_enabled = false       # enable background registration (default: off)
+farm_interval = 3600       # seconds between attempts per network
+farm_max_accounts = 10     # stop farming when this many verified accounts exist
+```
+
+## Channel Keys
+
+Channels with mode `+k` require a key to join. Configure keys in TOML:
+
+```toml
+[networks.libera]
+channels = ["#secret", "#public"]
+channel_keys = { "#secret" = "hunter2" }
+```
+
+Keys are used automatically during autojoin and KICK rejoin. To add a keyed
+channel at runtime:
+
+```
+/msg *bouncer AUTOJOIN libera +#secret hunter2
+```
+
+Removing a channel also clears its key:
+
+```
+/msg *bouncer AUTOJOIN libera -#secret
+```
+
+## DCC Stripping
+
+DCC requests (`DCC SEND`, `DCC CHAT`) embed the sender's real IP address in the
+protocol payload. The bouncer strips all DCC and non-ACTION CTCP messages in
+both directions:
+
+- **Inbound** (server to client): silently dropped, logged as warning
+- **Outbound** (client to server): blocked before reaching the network
+
+ACTION (`/me`) is preserved. This is a hard security boundary -- there is no
+config toggle to disable it.
+
+## Hot Reload
+
+The bouncer reloads its config file on `SIGHUP` or via the `REHASH` command.
+Both use the same logic: re-read TOML, diff networks (add/remove/reconnect),
+and update mutable fields (channels, channel_keys, nick, password).
+
+### SIGHUP
+
+```bash
+kill -HUP $(pidof bouncer)
+```
+
+Results are logged (no client connection needed). Useful for headless
+operation (systemd, containers).
+
+### REHASH command
+
+```
+/msg *bouncer REHASH
+```
+
+Results are sent back as NOTICE messages.
+
+### What changes on reload
+
+| Field | Effect |
+|-------|--------|
+| Network host/port/tls/proxy | Network reconnected |
+| channels, channel_keys, nick, password | Updated in-place |
+| notify_url, notify_cooldown, etc. | Notifier recreated |
+| farm_enabled, farm_interval, etc. | Farm started/stopped |
+| bind, port, password, client_tls | Warning logged (restart required) |
+
+## Systemd
+
+The bouncer ships with a systemd user service file. See [INSTALL.md](INSTALL.md)
+for setup. Key operations:
+
+```bash
+systemctl --user start bouncer        # start
+systemctl --user stop bouncer         # stop
+systemctl --user reload bouncer       # hot reload (SIGHUP)
+journalctl --user -u bouncer -f       # follow logs
+```
+
+The service restarts automatically on failure (`RestartSec=10`).
+
 ## Stopping
 
 Press `Ctrl+C` or send `SIGTERM`. The bouncer shuts down gracefully, closing
