Speed:
Option A — Current (bar blinks + dot scales to 120%)
3.5s resting → 0.5s pulse (bar blinks, dot scales 120%) → back
Production baseline. No glow — just the bar blink and dot scale.

Option B — Equal split $ ↔ s (wordmark reference only)
1.5s $ + 0.5s fade + 1.5s s + 0.5s fade = 4s
Wordmark alternating. For reference — not a glow candidate.

Options C–H — Scaling glow +100%: opacity × dot-scale matrix
Glow disc grows from r=8 → r=16 while fading in. Three opacities × with/without 120% dot scale.
All six use the same scaling glow approach (+100%, peak at 93.75%). Use Slow (8s) to see the expansion clearly.
Columns: left = accent dot also scales to 120%; right = dot is static.
C — 25% opacity + 120% dot scale
D — 25% opacity, dot static
E — 33% opacity + 120% dot scale
F — 33% opacity, dot static
G — 40% opacity + 120% dot scale
H — 40% opacity, dot static
Favicon preview — how the glow looks at actual tab sizes
Scaling glow +100% at 64px, 32px, and 16px
Using Option E (40% opacity + dot scale) as a preview. The glow disc grows from the dot centre outward.
At 16px (typical browser tab), the ring is ~1px — very subtle. At 64px (Apple touch icon), it's clearly noticeable.
Chrome and Firefox animate SVG favicons via embedded <style>. Safari shows a static first frame.

Alignment reference — $ vs s at multiple sizes
Left: $ showing. Right: s showing. Verify vertical alignment across sizes.
