/* =====================================================================
   ProDelta: "Earth, Overlaid" theme  (photo + data HUD)
   ---------------------------------------------------------------------
   PROGRAMMER NOTES
   - This file is loaded AFTER each page's inline <style>, so it overrides
     tokens and components without touching page markup. To roll the look
     back, remove the <link> to this file (and the .hud-* markup on index).
   - Everything is driven by the tokens in section 1. Change them here.
   - Fonts: Lora 700 (headlines, tool names, big numbers), Inter (body),
     JetBrains Mono (data labels). Loaded from Google Fonts for the preview.
     REPLACE: self-host woff2 files before launch for the PageSpeed target.
   - Textures (assets/images/hud-*.webp) are decorative, transparent WebP,
     used as CSS backgrounds only (no extra <img> requests).
   - Brand note: headlines are Lora Bold, all lowercase (per client).
