/*
THESIS: Keep the existing creation workstation intact and replace its neon glass skin with TapNow's quiet, content-first dark workspace.
OWN-WORLD: Near-black graphite field, solid #1d1d1d surfaces, restrained white hairlines, 16-20px corners, inset top highlights, and neutral controls.
STORY: The user's own image/video workflow remains immediately recognizable; surfaces recede, output media carries color, and state changes stay legible.
FIRST VIEWPORT: Existing brand, task rail, mode switcher, composer, settings, and send action keep their exact composition while adopting the new material system.
FORM: User-pinned TapNow reference applied as a CSS-only overlay; the incumbent layout is fixed, so no concept seed or replacement structure is used.
