 ### Dynamic Features
-```
-cache 0                                       # never cache (re-execute)
-source cpu : shell "cat /proc/loadavg"        # live data at render time
-source config : json "/path/config.json"      # JSON file read
-source ts : python "datetime.now().isoformat()" # Python expression
-let name = "Relay Alpha"                      # variable assignment
 
+Any page using `source`, `if`, `for`, `on_submit`, or `state` becomes **dynamic**: it compiles to an executable Python script instead of static Micron. NomadNet runs the script on each request and serves its stdout.
+
+#### Variables
+```
+let name = "Relay Alpha"                      # string assignment
+let threshold = 75                            # numeric
+let tags = "alpha","beta","gamma"             # comma-separated → list
+```
+Variables are substituted with `$name` in text, labels, and other content. They work in both static and dynamic pages.
+
+#### Data Sources
+```
+source var_name : type "command" [timeout=N]
+```
+Sources fetch data **at render time** and bind results to variables:
+
+| Type     | Description                          | Example                                                  |
+|----------|--------------------------------------|----------------------------------------------------------|
+| `shell`  | Run shell command, capture stdout    | `source cpu : shell "cat /proc/loadavg"`                 |
+| `file`   | Read file contents as string         | `source motd : file "/etc/motd"`                         |
+| `json`   | Read + parse JSON file → dict/list   | `source config : json "/etc/config.json"`                |
+| `python` | Evaluate Python expression           | `source ts : python "datetime.now().strftime('%H:%M')"` |
+| `http`   | HTTP request, auto-parses JSON       | `source data : http "https://api.example.com/data"`      |
+| `sqlite` | SQLite query → list of dicts         | `source users : sqlite "/path/db" "SELECT * FROM users"` |
+| `env`    | Read environment variable            | `source key : env "API_KEY"`                             |
+| `param`  | Read URL parameter from link         | `source hash : param "hash"`                             |
+| `rns`    | Query Reticulum via `rnstatus`       | `source peers : rns "peers"`                             |
+
+**Shell** commands have a default 5-second timeout (override with `timeout=N`).
+
+**Python** expressions have access to: `datetime` (the class, so `datetime.now()` works), `timedelta`, `secrets`, `os`, `json`. Expressions are evaluated via `eval()` — single expressions only, not statements.
+
+```
+# Python source examples
+source timestamp : python "datetime.now().strftime('%H:%M:%S')"
+source rand_id : python "secrets.token_hex(4)"
+source cpu_sim : python "secrets.randbelow(60) + 20"
+source uptime : python "str(timedelta(seconds=12345))"
+source hostname : python "os.uname().nodename"
+```
+
+**HTTP** requests return parsed JSON (dict/list) or raw string. Default timeout 10s.
+
+```
+# GET request — JSON auto-parsed into dict
+source todo : http "https://api.example.com/todos/1"
+text "Title: $todo.title"
+
+# POST with JSON body
+source result : http "https://api.example.com/search" method=POST body='{"q":"relay"}'
+
+# Custom headers (semicolon-separated)
+source data : http "https://api.example.com/data" headers='Authorization: Bearer tok123'
+
+# Use $var references in URL, headers, and body — resolved at runtime
+source token : env "API_TOKEN"
+source data : http "https://api.example.com/data" headers='Authorization: Bearer $token'
+```
+
+**Env** reads server-side environment variables. Use this for secrets — tokens never appear in `.uf` source or compiled scripts.
+
+```
+source api_key : env "API_KEY"
+source db_pass : env "DB_PASSWORD"
+```
+
+**SQLite** queries return a list of dicts (or a single dict for one row). Uses Python stdlib `sqlite3`.
+
+```
+# Query returns list of dicts with column names as keys
+source nodes : sqlite "/data/network.db" "SELECT name, status, hops FROM nodes"
+
+# Iterate results
+for node in $nodes
+  label "$node.name" "$node.status ($node.hops hops)"
+
+# Single row queries return a dict directly
+source config : sqlite "/data/app.db" "SELECT value FROM config WHERE key='theme'"
+text "Theme: $config.value"
+```
+
+#### Conditionals
+```
 if $cpu > 90
   text "ALERT: CPU critical"
 elif $cpu > 75
   text "Warning: elevated"
+else
+  text "All clear"
+```
+Conditions are Python expressions. `$var` references resolve to the variable's value. Supports `>`, `<`, `>=`, `<=`, `==`, `!=`, `&&` (and), `||` (or).
 
+#### Loops
+```
 for peer in $peers
   status "$peer.name" $peer.state
-
-on_submit "search"
-  source results : shell "search.py '$query'"
-  text "$results"
-
-state "counter" "/tmp/counter.json"           # persistent JSON store
 ```
+Iterates over lists (from JSON sources), dicts (wrapped as single-item list), or newline-delimited strings (from shell output). Access nested fields with `$item.field`.
+
+#### Cache Control
+```
+cache 0                                       # never cache (re-execute every request)
+cache 300                                     # cache for 5 minutes
+```
+Emits the `#!c=N` header that NomadNet uses to control page caching.
+
+#### Form Submission Handling
+```
+on_submit "form_name"
+  # Runs when the named form is submitted
+  # Form field values are available as $field_name
+  source results : shell "search.py '$query'"
+  text "Found: $results"
+```
+Field values are read from `FIELD_*` environment variables set by NomadNet.
+
+#### Persistent State
+```
+state "counter" "/tmp/counter.json"           # load JSON into $counter
+```
+Loads a JSON file into a variable. Use `_save_state(path, data)` in the generated script to persist changes.
+
+#### Using Variables in Content
+```
+text "Hello, $name"                           # inline substitution
+label "CPU" "$cpu_pct%"                       # in labels
+gauge "CPU" $cpu_pct 100 28 warn=75 crit=90   # as gauge values
+status "$peer" $state                         # in status indicators
+link "View $name" "/page/detail.mu"           # in links
+```
+
+#### Generated Script Runtime
+
+The compiled script includes these helpers, available in `on_submit` and source blocks:
+
+| Helper                              | Description                                   |
+|-------------------------------------|-----------------------------------------------|
+| `_shell(cmd, timeout=5)`            | Execute shell command, return stdout          |
+| `_read_file(path)`                  | Read file contents                            |
+| `_read_json(path)`                  | Read + parse JSON file                        |
+| `_http(url, method, body, headers)` | HTTP request, auto-parse JSON response        |
+| `_sqlite(db_path, query)`           | SQLite query → list of dicts (or single dict) |
+| `_get_field(name, default)`         | Read submitted form field                     |
+| `_get_param(name, default)`         | Read URL parameter                            |
+| `_load_state(path)`                 | Load state from JSON file                     |
+| `_save_state(path, data)`           | Save state to JSON file                       |
+| `_iter(val)`                        | Make a value iterable (list/dict/string)      |

+pipeline. This means every layout feature (boxes, gauges, tables,
+sparklines) works identically in both static and dynamic pages.
