feat(hero): banner lettering, re-render the three staging shots; defer the rest to 0.9.0

Banner lettering (JIMMY KIMMEL LIVE): new Tools/gen/generate_banner_texture.py
draws the exact title with Pillow + Liberation Sans Bold - an image model would
mangle a trademark string, and Qwen-Image 2.1 is research-only. Gold JIMMY /
KIMMEL / LIVE stacked on a crimson ground. ue_hero_facade_import.py generalises
import_albedo to import_texture and wires the banner into M_Facade_Banner_Ref as
Base Color (tiling 1.0), replacing the flat dark tint with a brighter red per the
owner's 'less dark, more bright'.

Re-rendered all three ReviewMap staging shots (front, oblique, portals) and
updated their Screenshots/README.md status rows.

The hero facade rework is now closed at 'surface detail that reads at 45 m'. The
remaining elevation work - volute capital depth, lattice grille depth, and the
full realism pass - is deferred to 0.9.0 per the owner, and the 0.9.0 hero item
records the hand-off.

+"""Generate the JIMMY KIMMEL LIVE banner texture for the hero facade.
+
+The three event banners are flat panels; the lettering is text and cannot be
+read as geometry at 45 m. An image model would mangle a specific trademark
+string, so the text is drawn here with Pillow and a system font instead:
+deterministic, exact, and (unlike Qwen-Image 2.1) not research-only.
+
+The banner face is 1.35 m wide x 6.2 m tall (aspect 1:4.59). The texture is
+written at 512 x 2304 (aspect 1:4.5), a 2% stretch that is invisible at the
+review distance.
+
+    python3 Tools/gen/generate_banner_texture.py
+    python3 Tools/gen/generate_banner_texture.py --out Art/textures/generated/T_Banner_KIMMEL.png
+
+Requires Pillow (host-only tool, not a gate; standard library is not enough to
+rasterise a font). The text is a trademark reproduced for internal development
+review only - record it in THIRD_PARTY_NOTICES.md before any public build.
