/* Li-dream — design system v2 (Task 5) + page layouts
   Breakpoints: desktop >= 1200px, tablet 768–1199px, phone < 768px.
   v2 identity (spec §2): charcoal #1a1a1a header / hero, amber "energy" accent, light body.
   Type: display + figures in DIN-style Bahnschrift (Windows) / DIN Alternate (macOS) — the lettering of
   power-station displays and rating plates; body in the system UI face. No web fonts (no external CDN).
   Signature: the "readout" — segmented battery cells (hero readout, AI preview brand cells) that encode real data. */
