Blades named the file they were attached to. They now act as street
signs: for each corner of a folder's block, the building nearest that
corner gets a green blade on each wall facing the corner's two streets,
near the corner end, reading the folder path (shortened from the left
when long; the repository name at the root). Neighbouring blocks each
sign their own corner, so an intersection shows a different folder on
every side. Courtyard walls set back from the street are skipped, and
blades still shorten or disappear when a neighbour is too close. File
names remain on the flat wall and roof signs.
City labels were a 2D overlay that showed through buildings at street
level. labels.js rasterises each label once into a shelf-packed atlas
(partial texSubImage uploads, mipmapped for grazing angles), and a new
instanced quad pass draws them depth-tested but not depth-writing.
District names float above each district's tallest tower facing the
camera, file names sit on roofs near the focus, walls facing a walker
carry name signs repeated every 24 m, and street names are painted on
nearby kerbs. Walking up to the building in the crosshair shows its
source on the facing wall. Signs rebuild only when the focus, heading
or selection changes; an overflowing atlas is cleared and refilled with
the nearest labels first. Placement helpers are unit tested.
