 * you would skate: a polished marble floor for balance, a stair set for
 * discipline, reeds laid over by the wind for flow. They fill the card edge to
 * edge behind the words, so the card reads as one image-and-text unit rather
 * than icon, title, body.
 *
 * The photographs are CC0 / public domain, found through Openverse; that
 * licence asks for nothing, but assets/tenet-photos.txt records where each one
 * came from anyway. They are cropped square, converted to grey and pushed
 * through an S-curve before they are saved (see that file for the recipe):
 * the page is monochrome apart from one accent, and a colour cast — the marble
 * floor's green, the reeds' tan — reads as a mistake rather than as warmth.
 * The curve is there because a flat alpha over near-black compresses a
 * photograph's whole range into the bottom of the scale, so the range has to
 * be opened up first or every shot turns to mud.
 *
 * Two masks, intersected. The vertical one keeps the copy readable, and it is
 * not a cut: the picture stays faintly present behind the words and only comes
 * up to full below them. Where it ramps matters more than it looks. The copy
 * runs to a little past half the card's height, and a ramp that reached full
 * at the middle put the last two lines over a photograph at two thirds
 * strength — enough for the stair treads to cut straight through the text. So
 * it is held to about a third until 52% and only opens up after that, then
 * eases off again at the very bottom. The horizontal one takes the left and
 * right edges down to nothing. Between them the photograph never meets a card
 * edge at full strength, which is the whole difference between reading as a
 * crop onto something larger and as a rectangle pasted onto the page. */
