detector: grid-background variants, dash-prefix eyebrow, marquee rule, inset-shadow stripes

Four gaps from human review of gpt-5.6 eval artifacts:

1. codex-grid-background variants: the block scan now also matches the
   inverted end-of-tile hairline form (transparent calc(100% - Npx))
   and reads the tile cell from the background shorthand's `/ Npx Npx`
   slot, not just background-size declarations. A single hairline layer
   qualifies when tiled by a px pair cell (page-scale line field);
   percent-tiled single hairlines (background-size: 25% 100% rules on
   data-viz tracks/graphs) stay legal.

2. hero-eyebrow-chip branch C (dash-prefix): sentence-case, regular-
   weight microlabels above the h1 announced by a short chromatic
   ::before/::after bar (8-80px x 1-6px, accent fill). Static cascade
   marks dash-pseudo targets during rule collection; the browser path
   reads getComputedStyle(el, '::before'/'::after').

3. New `marquee` slop rule: <marquee> elements, and infinite animations
   bound to keyframes with >= 20 percentage points of X travel. Percent
   travel only — px-travel loops are bespoke product animations
   (waveform playheads, progress sweeps). Centered elements animating
   other properties (constant -50% X), non-infinite slide-ins, rotations,
   and pulses never qualify.

4. side-tab inset box-shadow variant: single-edge inset shadows
   (3-12px offset on one axis, no blur/spread, chromatic) drawn as
   stripes on cards/badges/menu items. Selection-state indicators
   ([aria-current], [aria-selected], [role=tab], active/current/selected
   hints, interaction states) stay exempt; the same stripe repeated
   unconditionally on every item flags. Narrow fixed-width glyphs
   (logo marks) are exempt. isTabContextElement narrowed to match:
   bare nav ancestry no longer blanket-exempts top/bottom border
   stripes — only explicit tab semantics or state markers do.

Browser bundle regenerated.
