A hidden rail sits inside the curtain niche, not as a surface rail on the membrane. Profile choice follows niche planning (`curtain-niche-planning`): track count, lit niche, harpoon or clip, length and wall/window junctions are known.
Steps: 1) Fixing — harpoon — CURTINA; clip — TISSURE. 2) Track count and rail install (including later install if the series allows). 3) Light in the niche or a plain niche without LED. 4) Kit: end caps, gliders/hooks, corners, tools — only from the chosen SKU catalogue. See `harpoon-vs-clip`, `series-curtina`.
Keep jobs separate: CURTINA/TISSURE = niche. Light lines and FLOATIA = other nodes. No invented universal rail — compatibility only on the SKU card.
On site: niche alignment, space for fabric and glider travel, access to the rail after tensioning, junction with the room perimeter. Dimensions only from drawing/catalogue.

### FAQ
Model first or niche planning? Planning first (`curtain-niche-planning`).
Nearest SKU without the drawing? No — tracks, light zone and rail seat differ inside the series.
