/* ============================================================
   EVVO Smart, evvosmart.com
   Redesigned 2026-10-13 against the design-taste-frontend skill.

   Design read: B2B product landing for solar plant owners, EPCs and
   O&M teams in India, serious engineering language, native CSS on the
   existing static stack, Geist type, restrained and motivated motion.
   Dials: DESIGN_VARIANCE 7, MOTION_INTENSITY 8 (raised for the hero on
   2026-10-13 at the user's request), VISUAL_DENSITY 4.

   Locks
   - Theme: one per visitor. Light by default, dark when the system asks
     for it or html[data-theme="dark"]; html[data-theme="light"] pins light.
   - Accent: brand orange only, HSL saturation under 80%. Green and red
     appear only as real state: the plant preview, form errors, send status.
   - Radius: --r-panel 16px for images, panels, cells, menus and the form;
     --r-control 10px for buttons, inputs, chips and icon tiles;
     --r-tag 6px for bar segments and the slider thumb. 2-3px only rounds
     the ends of hairlines and the corners of legend swatches.
   - Layers: --z-raise 1, --z-sticky 10, --z-nav 50, --z-menu 60, --z-skip 100.
   - Motion: transform and opacity only, gated on html.is-motion, which
     site.js sets unless prefers-reduced-motion or ?static=1.

/* ============================================================
   Motion layer. Every animation here has one job:
   - hero load-in: reading order (headline word by word, lead, actions, photo)
   - hero scroll depth: the message hands over to the plant as the page moves
   - reveals: sections arrive in story order as they enter the viewport
   - flow index fill and pipeline draw: data moving from plant to desk
   - deemed bar: the month's loss splitting by cause
   - preview packets: direction and size of the power flow
   - marquee: breadth of protocols without a long list
   - nav progress: where the reader is on a long page
   - heading masks: each section's message lands before its details
   - pipeline pulses: data travels one way, plant to desk
   - media lens and rooftop drift: the visual settles as its section arrives
   - chart wipe: the simulated day unfolds from morning to evening
   - spotlight borders and equipment lift: feedback under the pointer
