v1.3.0

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 whole filter
• --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 like filter: 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.

v1.2.0

Pulse: dynamic colors + synced glow

• Pulse inner/outside hue now rotates a full 360° continuously, so colors are no longer pinned to fixed edges (previously a ±30° ping-pong left red/orange in the top-right and green/blue on the left).
• The wide bloom halo now shares the same hue rotation as the core/stroke, keeping the large and small glows color-matched (most visible on blue/green transitions).
