A platform's ceiling may change a rule's resolution, never the rule. P3
had picocalc colour node names by *type* instead of by key, so a name's
colour there meant something different than it does on the desktop — the
node's kind, not its identity. Both platforms now run one rule: the key's
first byte picks the hue. The console just spends fewer of them.
node_style gains the binding the heat scale already had. Regular keeps
the full 256-hue wheel; picocalc snaps the same hue to its sixth of it —
the six chromatic bright slots, ~43 first bytes each. It returns the
slot's own hex rather than a color(N), so every downsample on the way out
(Rich's, and the fold's quantizer) lands on that exact slot instead of
guessing a neighbour, and the callers that read an RGB back out of a
style string keep working.
The type marks needed the opposite treatment: their hues are fixed, not
derived, and a naive nearest-RGB match drained the repeater's violet to
grey — a repeater read as an unknown node. They move to the theme's
type.* entries so each platform picks its slot deliberately, and a
braille raster resolves the same entry through theme.mark_rgb, so the
canvas marker and its Rich-drawn twin can't drift.
With names off the type registry, nothing reads it: Platform.name_colour
and core/nodetypes.py go, along with the three reception-layer feeders.

One frozen Platform spec (REGULAR/PICOCALC), resolved once at boot
(--platform flag > MESHTERM_PLATFORM env > /proc/device-tree/model
auto-detect > REGULAR) and read via get_platform()/set_platform() -
never a stale `from platforms import PLATFORM`, which the module
docstring calls out. `meshterm platform` reports the resolution and
everything it looked at.
Wires the two correctness bindings that matter before any flavour
work lands: width_reclaim off on PicoCalc's exact-width console
(session._reclaim_last_column, env override still wins), and the
emoji-width calibration probe skipped outright when a platform never
draws emoji.
tests/test_gallery.py renders all 16 screens the interactive menu
opens against REGULAR (72x24) and PICOCALC (53x26 live floor, 53x40
lux case), asserting no line overflows its platform - 35 passing
cases, 13 xfailed as a real P6 worklist (contacts, map, walk,
livefeed, remote_cli, path_composer). Also caught and left alone: the
map screen's footer hint already overflowed the *existing* 72-col
standard before this seam existed, unrelated to picocalc - xfailed
rather than fixed as a drive-by. tests/test_platforms.py unit-tests
the module directly; conftest.py gained an autouse fixture resetting
the platform between tests.
