Add four Star Trek / Lower Decks pages with a 3D printer red alert

LCARS ship status, the Cerritos duty roster from the agenda, a warp core
driven by solar power with Rutherford's advice, and a captain's log under
a viewscreen. Original pixel art in tools/trek_sprites.py.

When the 3D printer (Moonraker current_print_state, `printer`
substitution) is paused or in error, the panel jumps to LCARS Status in
red alert and holds the rotation until it carries on.

+## Star Trek pages
+
+Four animated pages aboard a Lower Decks-era ship, drawn by
+[components/el512/trek.cpp](components/el512/trek.cpp) with Antonio (standing in for
+the LCARS typeface), all in the rotation:
+
+- **LCARS Status**: elbows, blocks and pills around the ship's systems: power
+  distribution (solar, house, grid), environmental (four rooms), long range sensors
+  (weather), the fabrication bay (3D printer state), a stardate and a data cascade.
+- **Duty Roster**: the U.S.S. Cerritos roster: Mariner, Boimler, Tendi and Rutherford
+  each get one of your next agenda events as their assignment (or a chore of their
+  own), with a scrolling shipboard notice.
+- **Warp Core**: plasma pulses rush into the reaction chamber faster as solar power
+  rises; engineering readouts for core output, containment (what the house load leaves)
+  and the plasma injectors (grid), and Rutherford with advice. A grid import above 3 kW
+  is a core breach (it's the oven).
+- **Captain's Log**: a viewscreen at warp that drops out next to a planet, over a
+  captain's log typed from the weather, power and the next agenda event.
+
+**Red alert:** when the 3D printer (`printer` substitution, the Moonraker
+`current_print_state` sensor) goes to `paused` or `error`, the panel jumps to LCARS
+Status in red alert and holds the rotation until the printer carries on.
+
+The pixel art lives in [tools/trek_sprites.py](tools/trek_sprites.py).

+These pages are fan art: the pixel art, layouts and texts are original, and no material
