Plant view: toilets in the factory, link lands on doors, no separate trimmer

User feedback on the isometric view (October 2026):
- "the production hall is missing toilets": two sets. At the staff
  entry: women 2 WC, men 1 WC and 1 urinal, an accessible WC, basins.
  At the east end of the back aisle in the finishing block: women 2 WC,
  men 1 WC and 1 urinal, basins (proposed, not yet in the parametric
  plans). site-candidates.md gets a Toilets bullet with the Thai minimum
  (Ministerial Regulation No. 39 B.E. 2537, table 2; separate toilets for
  men, women and disabled staff under the welfare regulation B.E. 2548).
- "the door and the corridor is not aligned": the covered link now lands
  on doors at both ends, centred on it (factory entrance at the start of
  the visitor corridor, office lobby door on the north face, windows
  cleared); the corridor glass starts after the door; the stray staff
  door with no path is gone; the link deck ramps up to the factory floor.
- "we also dont need a extra trimmer with the optical, this is included
  in the duplex and the classics": the finishing block keeps only the
  optical inspection station; site-candidates.md, the tour route and the
  process flow say the presses trim inline.

Checks: renderer 720 checks and functional checks pass (max 2,485 SVG
nodes); calculator regression 0 fails; level selector works in the page;
no page errors or overflow at 390 / 1024 / 1440 px, dark and light.
