Cause: the monochrome-first treatment from #351 flattened the emoji
artwork through an alpha mask (transparent fill + zero-offset
text-shadow), dropping internal details (the ghost lost its tongue and
eyes), and the watermark box did not occupy the full space available
above the chat composer.
Fix: new .project-cell-illustration-area container (container-type:
size) wrapping the scroll zone so the absolute watermark spans the
whole region between the agent toolbar and the composer; glyph keeps
the OS full-colour emoji artwork as source and is neutralised with a
non-destructive CSS filter (grayscale(1) contrast(0.92)) so internal
tones and details stay visible in black and white; glyph sized to
min(100cqw - 8px, 100cqh - 12px); text-variation selector U+FE0E
stripping removed (full emoji preserved) and project-theme tint
plumbing (accessibleProjectAccent/onProjectThemeChanged) dropped as
superseded by grayscale; empty label and overlay z-layering untouched.
