Pulse-outside consumer tuning hooks
Adds opt-in CSS custom-property hooks for the pulse variants, all with backward-compatible defaults:
--pulse-glow-boost— relative multiplier on the measured glow reach--beam-core-blur/--beam-bloom-blur— tune glow blur without overriding the wholefilter--beam-glow-brightness/--beam-glow-saturate— glow intensity--beam-inner-opacity/--beam-bloom-opacity/--beam-stroke-opacity— per-layer opacity (scales the real layer opacity, not clamped likefilter: opacity())--beam-hue-base— hue offset that keeps the wide glow color-synced with the 1px stroke ring
No changes to default rendering for existing users.
