Plugin docs page (/plugin):
- Hero, feature grid, numbered install guide, screenshot gallery, install CTA
- Navbar 'Plugin' link added
- Screenshot slots with placeholders for 6 captures (flip HAS_SCREENSHOT
once PNGs are dropped into /public/plugin/)
- Structured data (SoftwareApplication) + breadcrumbs
TDP fix:
- Add 3W fixed overhead to CPU+GPU power for screen/fan/speakers/peripherals
so reported TDP is closer to total system power draw
