feat(hero): first pass from the masonic-temple reference folder

Art/reference/hero-masonic/ (15 images, git-ignored) replaces the single Wikimedia photo as the source of
truth. Two front elevations drive this pass: 02-masonictemple01.jpg, a clean street-level frontal, and
06-el-capitan-theater-frontal-fachade.jpg; 05-hollywoodmasonictemple-1922.jpg records the original masonry.

Changes:

- the blank Hero_Stylobate_LintelBand across the portals is removed - the reference has open doorways with
  steps, and they now read as three dark openings with banners above them;
- rustication(): five ashlar courses from the pavement to the portal heads, 4 cm joints proud of the wall;
- balustrade(): bottom rail, top rail and 38 balusters along the roof edge, where the reference shows a
  cresting and railing.

Still missing against the same references, and recorded: warm sandstone instead of flat pale stone, lattice
grilles in the window bays, the carved inscription, and medallions that do not read at distance.

The blend is read-only after a checkout - chmod u+w first or the save fails silently and the FBX is never
written, which happened once here.

Rows 4-6 re-rendered and pending review.
