Pricing — 6 minimal concepts

Side-by-side Free/Pro hairline panels with big mono prices, five label/value spec rows split by hairlines, and a CSS-only monthly/annual radio toggle ("2 months free" note lights up blue on annual; "$120 billed annually" fades in under the Pro price). Pro carries the blue accent border, faint glow, MOST POPULAR pill, and solid-blue CTA. Cards stack single-column below 760px with zero overflow at 360px; reduced-motion kills all transitions; ~18 visible words (39 counting every non-numeric token).

One ruled table with spec-sheet energy: prices fused into the column heads as display numerals ($0 vs $12/mo with $10/mo annual sub-line), five hairline capability rows with mono values (1 vs 100, Email + SMS vs + Webhook, 2 per alert vs 20 per channel, 1 min – 2 hr vs 1 min – 100 yr, — vs Full API), CTA links in the foot. Pro column gets a flat blue wash plus a 1px blue cap; the single ember moment is the bottom rule terminating in a glowing node, echoing the pulse-timeline trigger. No toggle (static dual price), no animation (only hover color/arrow transitions, nulled under prefers-reduced-motion), responsive 360→1440 with zero overflow. About 22 visible words counting generously.

Pro-only pricing altar: a CSS-only billing dial (hidden radios + sliding tick-ruler + pointer) flips a huge JetBrains Mono readout between $12/mo and $10/mo "billed annually — 2 months free" (the one ember moment), with a solid-blue Get Pro CTA, a hairline 5-cell Pro spec strip, and Free reduced to one quiet line. Defaults to monthly, keyboard-accessible (arrow keys + focus rings), spec strip collapses to a right-aligned spec sheet below 840px, zero overflow 360–1440, and reduced-motion disables all transitions. Roughly 24 visible words excluding micro-labels and mono data.

Two till printouts side by side: a large emphasized Pro receipt (dotted-leader line items, double-dashed rule before a big blue-soft $12/mo total, annual line with "2 months free", solid-blue mono CTA, fake barcode, ember "*** fires on silence ***" footer) and a smaller staggered Free stub with a dashed ghost CTA. No toggle — both prices shown statically. Stacks to a centered single column below 760px (Pro first); the only animation is a gentle ember-note opacity pulse, stilled under prefers-reduced-motion. About 16 visible words (excluding micro-labels and mono data readouts).

Full-bleed 50/50 pricing slab divided by one vertical hairline with a single ember switch-node at its center: Free sits dim on the left, Pro lit under a blue radial wash on the right, each side a mono spec sheet (price display, five dotted-leader rows, block CTA) whose rows align straight across the axis. No toggle — static dual pricing ($12/mo display, "$10/mo billed annually · 2 months free" sub-line); below 760px it stacks Pro-first and the divider rotates horizontal with the ember node riding it; the ember's slow flare ping stills under prefers-reduced-motion. About 15 countable visible words (62 tokens total including all micro-labels and mono data readouts — under the 80 cap even with zero exclusions).

A single hairline-framed horizontal band: kicker + "Start free. Upgrade when it matters." on the left, FREE $0 and PRO $12/mo chips with subgrid-aligned mono limit triads in the center, ghost/solid CTAs on the right; no billing toggle (annual shown statically as "$10/mo annual · 2 months free" in the single ember moment). Stacks to three rows under 940px with chips staying 2-up at 360px, zero horizontal overflow 360–1440, and the only animation — a 9s blue signal riding the top hairline — is hidden under prefers-reduced-motion. ~22 visible words.
