Features — 6 minimal concepts

An engineering-datasheet features table: six hairline-ruled rows with Space Grotesk parameter names, dim Inter Tight terse lines, and right-aligned JetBrains Mono value readouts under a PARAMETER/DESCRIPTION/VALUE header rule, topped by the shared kicker+dash and a "DS-01 · FEATURE SET" doc-ID. Fully responsive 360→1440 (4-col sheet → name/value baseline rows → stacked mobile readouts) with zero overflow; the only motion is a blinking block cursor after the curl readout, stilled under prefers-reduced-motion. 54 visible words.

The safe-baseline 3x2 capability grid done with restraint: hairline-bordered tiles carrying only a 24px stroke glyph, a Space Grotesk name, and one terse line; hover brightens the hairline and tints the glyph blue. Fully static (no keyframes), collapses 3→2→1 columns at 920/560px with zero horizontal overflow from 360px, transitions disabled under reduced motion. 54 visible words.

The section IS the architecture drawing: four check-in channels (tap, email link, SMS reply, API) converge on one switch node; three actions fan out as the single ember fire moment. Remaining capabilities (intervals, reliability, recipients) sit on a spec strip beneath. Stacks vertically on mobile; CSS-only, reduced-motion honored.

Sticky kicker + headline on the left; six hairline rows on the right with large Space Grotesk feature names, JetBrains Mono spec values beneath, and right-aligned solid-ghost numerals 01–06 (deliberately the inverse of How It Works' left-side outlined figures). Stacks to a single column below 880px with the header static; hover-only transitions are zeroed under prefers-reduced-motion. 18 visible words.

Six feature "components" seated on a faint circuit: each chip (glyph + 2-word mono name + mono spec readout + terse caption) drops a hairline connector onto a shared signal bus, where a slow blue check-in pulse travels and is absorbed at the single ember via — the point where the warm trigger trace exits the board past a TRIGGER tag. Below 720px the bus, connectors and captions disappear and chips stack in a clean 2-col grid (glyph + name + spec only); prefers-reduced-motion stills the pulse and via flare, leaving a static ember glow. 41 visible words.

Six numbers-first instrument readouts in one hairline-framed band with a status strip: each cell leads with a large mono spec value, feature name demoted to a micro-label, and a tick-scale gauge whose needle sways gently (stilled under reduced motion). Collapses 3x2 → 2x3 (≤880px) → 1-col (≤620px) with verified zero horizontal overflow at 360–1440px. 5 visible words excluding micro-labels/spec values (~46 counting every visible token).
