/*
THESIS: The page is someone doing the electricity math for you on a yellow sheet: the answer circled in red pen, a note scribbled beside it. Refuses the calculator-site default of cards, gradients and a "Calcular" button.
OWN-WORLD: Safety yellow ground, black ink, Barlow at 800 for answers and headings, hairline rules between rows, red marker (Gochi Hand + hand-drawn SVG strokes) used once or twice per page.
STORY: The visitor reads the circled monthly cost, sees the scribbled difference if the flag turns red, and trusts it because the source line names the official resolution.
FIRST VIEWPORT: Wordmark and month/flag line, H1 question, ruled field rows with a working default, circled result with the marker note.
FORM: Conta riscada à mão (user-chosen A3, photo removed). Country-agnostic: colors of scenarios and all copy come from the country pack.
