/* UVIRA website (local prototype): one stylesheet for every page.
 *
 * Design rules, so later pages stay in the family:
 *  - Brand: navy #14336B carries actions and type; copper (#8A4B1B, #C98A55 on dark) marks movement only: flight
 *    paths, progress, the stock meter and the 28 % / 72 % brand rule line under the header.
 *  - Type: IBM Plex Sans for everything, IBM Plex Mono for things you might copy or compare (order numbers,
 *    serials, codes, amounts in tables, specs).
 *    Copper is never a section rule, a callout stripe or a label colour (S166): one accent, navy.
 *  - Corners: buttons and inputs 10px (--r-btn), cards and panels 16px (--r-card), small panels inside a section
 *    (steps, notes) 12px (--r-panel-sm), films and pictures 18px (--r-media), chips and badges fully round. Small
 *    thumbnails inside a control may use 6px. Nothing else.
 *  - Pictures: one picture, one place on the selling pages (home, IFC 1.3, Studio, School, Students, Pricing,
 *    Marketplace, Download); the documents may repeat the board render. A Studio picture is one region of the window
 *    (the 3D view, the blocks, one chart) at 16:10, never the whole window below 900 px wide.
 *  - Motion answers an action or tells a story once (the hero); prefers-reduced-motion turns it all off.
 *  - Words: headings in Title Case on the selling pages, sentence case in the documents (S102, kept in S166).
