/*
 * miguelbrito.solutions - lead magnet landing for «Punto Final».
 *
 * Design read: lead-magnet landing for Spanish YouTube viewers curious about
 * building games with AI, with a typewriter/dossier editorial language from
 * the video «Punto Final», native HTML + CSS + a few lines of vanilla JS.
 * Dials: DESIGN_VARIANCE 7 / MOTION_INTENSITY 5 / VISUAL_DENSITY 3.
 *
 * Justified overrides of taste-skill defaults:
 * - Palette: ink #141210, cream #EFE6D2, paper shadow #D6C9AC and a single
 *   accent red #C3212B. This is the brand identity of the video (the red dot
 *   of the game logo and the "PERDISTE" screen), not a premium-consumer
 *   default. Amber is never used on the page; it only appears inside the real
 *   game screenshot. In dark mode, small red TEXT (errors) uses a lighter
 *   tint of the same hue (#F06A6F) because #C3212B on ink is only 3.2:1.
 * - Fonts: Anton (display, uppercase) + Courier Prime (all body and UI, the
 *   typewriter voice of the game). No serif. Self-hosted, OFL licensed.
 * - Theme: auto via prefers-color-scheme. Light = cream paper page, ink text.
 *   Dark = ink page, cream text. Same hierarchy in both.
 * - Shape: all-sharp. Every corner radius on the page is 0 (paper/dossier).
 *
 * Contrast notes (WCAG): cream on red button 4.74:1, red on cream 4.74:1,
 * ink on cream 15.9:1, muted #4A443B on cream 7.7:1, muted #B8AE98 on ink
 * 8.5:1, red focus ring on cream 4.7:1, tinted
 * focus ring #F06A6F on ink 6.2:1.
 *
 * Z-index scale: 1 = content lift, 10 = skip link, 50 = paper grain overlay.
 *
 * Access page (acceso.html): same system. Dials 6 / 4 / 4 (utility page that
 * delivers instructions). Code blocks are ink on the light page and a lifted
 * ink (#1C1916) on the dark page, cream text in both (15.9:1 / 14.6:1).
 * Brand marks in buttons are Simple Icons 16.35.0 SVGs (CC0 1.0), vendored in
 * assets/icons and painted with currentColor through CSS masks.
