Add trouble-targeting business fixtures: fitness studio, travel tours, accounting firm (86-88)

[chubes4]

Three realistic business fixtures deliberately built from the SSI fixture matrix's currently-measured failure families — scroll-reveal sections, inline SVG art (gradients/defs), styling-dependent rendering, mid-page forms, stretched-link cards, runtime islands (counters/carousels/tabs), and pricing/comparison tables with toggles:

• 86-fitness-studio (complexity 3): animated stat counters, sticky-column schedule table, trainer carousel, monthly/annual pricing toggle with CSS fallback, gradient bg-image hero, trial form, stretched-link class cards.
• 87-travel-tours (complexity 4): layered inline-SVG hero scenery, overlay tour cards with badges + whole-card links, CSS timeline spine, masonry gallery, testimonial slider, currency/date booking form, native details FAQ, reveal on every section.
• 88-accounting-firm (complexity 3): 3-tier comparison table with SVG checkmarks, animated counters, hover-reveal team overlays, radio-input CSS tabs + JS enhancement, consultation form, SVG client logo strip, shrinking sticky header.

All manifested (marketing/static, capabilities [forms, local-css, runtime-js], risk medium), self-contained/egress-free, progressive-enhancement JS. Every pattern is something real businesses ship — no contrived markup. Discovery verified: 80 fixtures, 0 unknown classes.
