review: split the rounds into named shots and stage the player pawn

Roadmap gains two sections: 'Review scene and player placement' (this pass) and
'Character development' (follow-on). The camera list is now one table of
(name, location, target) with look-at rotations computed from the pairs, so a
camera cannot drift out of aim when one number changes.

New shots: player-placement (the real pawn, staged in the build script),
ground-contact (knee height, feet on the plane), shadow-compare (floating vs
grounded cube from a low angle), and hero-portals (whole elevation).

The review floor grows to 160 m so the facade stands on ground rather than the
horizon band. Retired: the first-person shot.

Honest gap recorded in the roadmap: the hero portals sit behind the colonnade and
do not resolve from the review floor; that needs a camera on the plinth or a
portal rebuild, not another angle.
