  flare style
Glow, spikes and flare (halo rings, 16 ghosts, and one of three styles: C subtle halo + ghosts, A anamorphic streak, B soft starburst, all scaled to the star's disc and dimmed for faint stars; "extra flares" sets how strong the extended stack is) are one full-screen pass driven by the star's screen position and blocked by whatever covers it. Bloom / tone map / vignette / grain / CA run through an effect composer; with all five off it is bypassed (no cost).
