/* Public questionnaire + /verifica styles. Mobile-first (360px), no external resources.
   Look: Roman sand + brick red, editorial. Sand for backgrounds and surfaces, brick for buttons,
   highlights and graphic details. A restrained "liquid glass" layer (frosted, slightly transparent
   cards with a thin luminous edge) is used only on the top bar, the large landing cards and the questions'
   sticky action bar; question options, inputs and forms stay on near-opaque surfaces so they are always easy to read.

/* Contrast (WCAG 2.2 AA), computed on the EFFECTIVE colour of each surface. Glass = --glass composited
   over the darkest thing that can sit behind it (light: pure brick #a33c27 for the landing cards, black for
   the prize card over the photo; dark: brick #b4462f, white for the prize card).
   Light  — text: 15.3 surface · 12.6 bg · 10.5 glass-worst; --text-2 ≥ 7.4; --muted ≥ 5.2; --brick-ink ≥ 5.0;
            white on --brick 6.5 (hover 8.3); --border-strong ≥ 3.5 everywhere (4.2 on bg).

            --brick-edge (outline of brick fills) vs dark glass 5.1.
   Prize card + how-to card (both --glass-strong) over the raw photo, worst case #1a1a1a…#f5f5f5, no tint:

   Prize teaser pill: brick-ink on brick-soft 6.0 light / 6.9 dark.
   Question phase (sticky action bar = --bar, 90% opaque; worst case = bar over dark text / brick / black (light) or
   white / terracotta (dark)):
   Light — text on bar ≥ 10.1 · pip outline 3.5 · pip fill 4.3 · progress fill vs empty segment 3.8 · pending Next label
           (brick-ink on brick-soft) 6.0, its edge vs bar ≥ 4.8 · max-reached pill text 13.7 · error badge 6.2 · error text 7.2 ·

           segment edge vs soft fill 5.2 · "answer missing" text / row edge 7.2 · selected-country pill edge vs bar ≥ 4.2.
   Dark  — text on bar ≥ 12.1 · pip outline 3.9 · pip fill 5.8 · progress fill vs empty 4.3 · pending Next 6.9, edge ≥ 7.1 ·
