- On non-Bambu printers `use_generic_ams_layout()` routes `GENERIC_AMS` units through a variable-lane
rendering that draws one lane per reported tray; Bambu keeps its fixed four-slot rendering.
- `AMSControl` picks its layout by vendor: Bambu keeps the left/right presentation
(`CreateAmsSingleNozzle` for one toolhead, `CreateAmsDoubleNozzle` for two), while non-Bambu
printers use `CreateAmsMultiNozzle`, which builds one preview and one AMS simplebook per toolhead
for any count.
- `AMSControl` picks its layout by toolhead count, not vendor: `CreateAmsSingleNozzle` for one
toolhead, `CreateAmsDoubleNozzle` for two, and `CreateAmsMultiNozzle` (one preview and one AMS
simplebook per toolhead) for three or more. A two-toolhead generic printer therefore keeps the
legacy left/right presentation; that is deliberate.
- The status panel's `ExtruderImage` renders one per-toolhead state per nozzle and is resized to
`GetTotalExtderCount()`. Non-Bambu printers choose the active toolhead through
`m_generic_nozzle_selector` (shown when more than one toolhead exists); Bambu keeps its left/right

- **Extruder dialect invariants.** `device.extruder.state`'s count field must equal the length of
`info[]`, and `info[]` must be ordered by extruder id with `id` equal to the array index: the
parser places toolheads by array position while `GetExtderById()` indexes by id.
- **One filament road per toolhead.** Each toolhead renders a single AMS filament road rather than an
independent per-toolhead road state. A generic scaffold that allowed the latter was removed as
unused; the one-extruder-per-toolhead road is the intended model.
- **Preset/device agreement.** The generic layout and virtual-slot range derive their count from the
selected printer preset. A printer preset must therefore declare the same number of
`nozzle_diameter` entries as the device has toolheads; a mismatch is surfaced because the sidebar
and extruder logic would otherwise disagree.
`nozzle_diameter` entries as the device has toolheads. A mismatch is surfaced only as a log warning
(`StatusPanel::check_extruder_count_mismatch()`), deliberately log-only, because the sidebar and
extruder logic would otherwise silently disagree.
- **Bambu compatibility.** Bambu-specific presentation (left/right pair, fixed 4-slot units, fixed
virtual ids, physical/logical inversion) is preserved behind the vendor check. Generic paths do
not alter it.
