## Acceptance Criteria
- [ ] Pixel Operator asset location and format are verified.
- [ ] Hub text rendering uses Pixel Operator when the existing rendering path supports it.
- [ ] If deferred, the reason is recorded and `PLN-0064` remains executable.
- [ ] No broad font/text toolkit is introduced.
- [ ] Text remains legible at 270p.

- `assets/pixel_operator*`
- `crates/console/prometeu-system/src/programs/prometeu_hub/`
- Existing HAL/GFX/asset modules if they already host font or glyph rendering
## Execution Notes
The asset is present under `assets/pixel-operator/` as TrueType files, including:
- `PixelOperator.ttf`
- `PixelOperator8.ttf`
- `PixelOperatorMono.ttf`
- `PixelOperatorMono8.ttf`
The included license is CC0 1.0 Universal.
The current runtime text path does not have a TTF loader, font manager, glyph rasterizer, or asset-backed font registration path. Hub/System UI currently reaches text through `GfxBridge::draw_text`, backed by the built-in 3x5 bitmap glyph path in `crates/console/prometeu-drivers/src/gfx.rs`.
Because `DEC-0028` explicitly forbids expanding this wave into a broad toolkit and this plan forbids introducing a general font manager/text engine, Pixel Operator rendering is deferred. `PLN-0064` remains executable and tested with the existing bitmap text path, which is already pixel-style and legible at 270p.
