/* Paper Trader: the design language of the Tesla · SpaceX · xAI deck (Tesla_SpaceX_xAI_Structural_Integration_Analysis_v6),
   made a little more technical, like a Bloomberg page (the user's request, 7 Oct 2026: "i want hummingbird to have its own
   distinct look. Use the design language from the tesla slide deck and make it look slightly more technical like a
   bloomberg page"). From the deck: a near-black navy title band with faint rings, red letter-spaced kickers, bold serif
   titles and big serif figures, light grey panels under dark header bars, dark-header tables with banded rows, an italic
   sources line, a letter-spaced footer. From Bloomberg: a live ticker strip, fixed-width figures and timestamps, section
   heads under a heavy rule, dense tables, change badges with arrows.
   Since 7 Oct 2026 the whole page sits on the deck's navy ("make the navy blue the background instead of white"): one dark
   look, not a theme that follows the viewer's setting. Panels are a lighter navy, header bars the deck's #1c2540, small red
   text a lifted red (#ff4d66) so it reads on navy; the deck red stays for fills, rules and the chart line. Text contrast is
   at least 4.5:1 on every surface; the chart pair passes the dataviz validator in dark mode on the page and the panel.
   Since 7 Oct 2026 the career design system is sans only (Calibri for everything, no Cambria or serif): --serif now holds
   the sans stack, kept as a name so every rule that uses it follows. */
