/* AI Marketer Club tools: shared look for every tool page.
   Light business look (changed 12 November 2026, Achuth's call): white page, near-black text,
   ONE violet accent used sparingly to guide the eye: the headline result, the chosen mode,
   the main button and keyboard focus. Green, amber and red only ever mean good, short and loss.
   Fonts: Fraunces (headings), Inter Tight (everything else). */
