/* HSM SOFTWARE MASCOT — the character that travels with the visitor: the
   visual cursor on desktop, a scroll-driven flyer on touch, and the thing
   that lands above the Send Message button. js/hsm-mascot.js builds the
   layers and owns every transform; this file only sizes, stacks and colours:
     #hsm-mascot          fixed 0×size box whose origin is the character's
                          chest — the one point the controller moves (one
                          transform per frame: position, lean, scale, float)
     .hsm-mascot__glow    HSM-blue aura that lags the body a little (JS translate)
     .hsm-mascot__trail   HSM-blue streak behind the body while flying
     .hsm-mascot__pose    one <img> per pose, crossfaded by .is-active
     .hsm-hotspot         the real pointer position while the mascot is the
                          cursor (sibling, so it never inherits the lag)
   Nothing here animates left/top. Every coloured effect (aura, trail, ring,
   landing glow, shadow tint, hotspot) is an alpha of the fixed --hsm-blue-rgb
   brand token; light/dark only changes intensity via --hsm-glow-a,
   --hsm-trail-a and --hsm-shadow. The artwork is never hue-shifted or
   recoloured: the suit, visor and HSM branding stay as drawn. */
