Bare or stale: `public, max-age=300`. +3. Then the store, as above: memory, file, draw. The crawlers a new link sends at once (Discord, + Slack, Mastodon instances...) share one draw. Nothing drawable is answered 404. + +When a portrait changes, its fingerprint and so its address change: chat apps that cached the old +picture under the old address fetch the new one, and nothing has to be purged. + +## Strand fields + +The build step writes `.strands.png` beside each hair piece. Without it (running from +source, or a deploy that skipped the step), `orcpub.portrait-pack.strands/worked-out-png` works +the same PNG out from the art once and keeps it. Both consumers read those bytes, the builder over +HTTP (`/image/portraits/...strands.png`) and the server renderer directly, so a deploy without the +files draws exactly what one with them draws (`portrait-render-test` checks it pixel for pixel). +The renderer keeps the parsed fields in their own cache. + +## Seeded randomness + +Everything that must come out the same in the browser and on the server goes through +`orcpub.dnd.e5.portrait-random`: Randomize's seed hash (FNV-1a) and generator (mulberry32), and +the grid hash behind hair streaks and freckles. Plain `*` and `(int c)` differ in ClojureScript, +which once made every browser Randomize return the same portrait. One-off UI randomness +(`rand-int`, `shuffle` in the character randomizer) and secrets (`SecureRandom`, UUIDs) are +different jobs and stay where they are. + +## Artist credits in the browser + +Artists can edit their credit, so it never goes into the page's HTML or a script. The browser +fetches `/dnd/5e/portrait-artists` (JSON, cached a minute) at start, keeps it in app-db under +`:portrait/artist-overrides`, and every view that shows a credit subscribes to it, so a credit +drawn before the fetch updates when it lands. Until then the views, and a PDF exported in that +moment, show the registry's public default. Server-side pictures and share cards read the same +merge (`artist-credit/refresh!`) directly. + +## What the browser does instead + +The builder draws on a canvas; the PDF export posts the portrait the browser baked (it goes back +only to the person who asked, so the browser's pixels are trusted there and nowhere else).

The portrait frame stays dark in both themes: what it holds is +character colours, pale skin and blonde hair among them, which a light frame would swallow. + +**The empty slot.** The empty frame and thumbnail use a shallow top-down gradient, like the app's +other panels, and carry the site logo debossed: masked to about 5% white with a one-pixel shadow +under it. Only the empty states carry it, so a portrait never shows a logo through its transparent +parts. The logo comes from `branding/logo-path`, so a fork shows its own.

Multiplying the whole eye layer tints +the sclera and the lashes along with the iris. + +Two things were tried and rejected: + +- **Additive blending.** The artwork shows through, so shading and the + highlight wash toward white. The result looks *transparent* -- this is what + "the iris colours are see-through" was describing, and it is not a property of + colouring the iris, only of adding to it. +- **Runtime iris detection.** Fragile on stylised art, and it has to run on + every render for a fact that never changes. + +What ships instead: the iris region is **authored once per asset** in the Loom +and stored in the registry as `:asset/iris` / `:asset/pupil` on each eye style +(`portrait_assets.cljc`) -- an ellipse, a pupil radius, a pupil offset, and a lid +curve per eye -- and the renderer maps the drawing's own luminance through the +chosen colour inside it. + +All three renderers do this, from one module, `portrait_colorize.cljc`: the maths +and the region geometry live there, and only the pixel loop and the drawing of +the region are per renderer. The share card fills the region with Java2D; the +builder's drawer and the PDF bake fill it on a canvas, and the drawer shows those +layers as `` elements with `object-fit: contain`, since CSS can't map +luminance through a colour. The lips use the same function over the whole asset. +An eye style with no placed region is multiplied instead, because colouring the +whole asset would paint the whites and the lashes too. Dark stays dark, mid becomes the colour, the highlight stays a +highlight. It is opaque where the drawing is opaque. + +The region is rasterised **antialiased** (`Graphics2D.fill` with +`KEY_ANTIALIASING`), not tested with `Area.contains`. `contains` is a yes-or-no +test, so the iris and pupil edges came out stair-stepped against artwork that is +smooth everywhere else -- invisible at portrait size and very visible on a +printed sheet. The antialiased coverage becomes a per-pixel blend weight, so the +region's edge fades into the drawing instead of stepping. + +## Floor and gamma: two viewing distances, two knobs + +The luminance ramp has a **floor** -- how much of the eye colour the darkest +iris ink keeps. On art whose irises are drawn almost black, a low floor loses +the colour entirely and the eye reads grey. + +Raising the floor was doing two jobs at once, and they pull apart: + +- a glance across the room integrates the iris into one average colour, so + distance legibility is its **mean**; +- a close look sees the shading inside it, so how modelled it looks is the + **spread** between its darkest and lightest ink. + +Raising the floor lifts the mean *by squeezing the ramp*, which costs the +spread. Measured over the placed iris region of the sample pack: + +| setting | mean | spread | +|---|---|---| +| floor 0.55, gamma 1.0 | 0.249 | 0.065 | +| floor 0.75, gamma 1.0 | 0.311 | 0.035 | +| **floor 0.55, gamma 0.5** | **0.309** | **0.114** | + +The first two rows are the trade: the mean goes up a quarter and the spread +halves. This is why floor 0.55 looked better up close and floor 0.75 better at a +distance -- **both observations were correct**, and no single floor could serve +both. + +The fix is a second knob. A gamma below 1 applied to the drawing's luminance +*before* the ramp reads it lifts the midtones -- where the body of the iris sits +-- while leaving the darkest ink alone. The third row is as bright on average as +floor 0.75 while keeping nearly twice the tonal range of floor 0.55. + +**Settled: floor 0.55, gamma 0.5.** Raising the floor further past this buys +very little mean and costs spread quickly; dropping the gamma below ~0.4 starts +to look harsh. Both numbers are tuned to art with near-black irises and should +be re-measured if a second illustrator's work comes in with lighter ones. + +## Colour slot presets + +The eye slot is the one that needed the most saturation: at portrait size an +iris is a few dozen pixels and a muted hue does not read as a colour at all. +Per-slot boosts over the first presets were eyes x1.45 saturation / x1.22 value, +shirt x1.22 / x1.08, hair x1.18 / x1.06, skin x1.06 / x1.02 -- skin barely +moves, because skin is the slot where a boost reads as sunburn. + +## Hair streaks follow the drawn strands + +The ombré's Streaks setting moves where the tip colour starts, strand by +strand. It was first a wave of horizontal position only, so every streak was +a vertical stripe. On long straight hair that passed, but on the short cut, +which is swept and curled all over, it read as paint on glass. + +**Reversal:** streaks are no longer a function of x alone. `strand-field` in +`portrait_effects.cljc` reads the strand direction from the linework (the +smoothed structure tensor of the ink; the lines run along the strands). It +points that direction away from the crown and falls back to "outward from the +crown" where nothing is drawn. It then averages noise along that direction +(line integral convolution). + +- **Cost:** about 200ms per piece on the JVM at 1200x1500, on a 4px grid. + Nearly all of the first 400ms was a box blur whose local helper fns boxed + every value; plain index arithmetic halved it. +- **Worked out once, ahead of time:** the field depends only on the art, not + on the head or the colours. It is computed in the art's own pixels, with + the crown taken from the piece itself, and written beside the art by + `orcpub.portrait-pack.strands` (see PORTRAIT-PACK.md). The share card maps + its frame pixels back through the art's placement, so all three renderers + read the same field. Without the file, a renderer computes the field once + and keeps it. +- **Identical renderers:** the noise hash is 32-bit integer maths + (`Math.imul` in JS, `unchecked-multiply-int` on the JVM). A test pins its + values, so every renderer streaks the same way. +- **Bug to avoid:** a direction field has no sign, so each step of the walk + keeps the heading of the last *field* direction, not the last *motion*. + Comparing against motion flipped the backward walk at every step, and the + smear went back and forth on the spot. That produced blotches, not streaks. + +## Eye and skin effects, hair shine and split + +All in shared cljc (`portrait_face.cljc` for eyes and skin, `portrait_effects.cljc` +for hair), so the share card, the builder and the PDF draw them identically. + +- **Light from below (always on):** the lower part of each iris is lifted in + its own colour, the way light comes through a real iris. No catchlight is + added: the art already draws one beside the pupil, and a second highlight + read as salt on the real art, however it was shaped. +- **Second eye colour** goes to the eye on the right of the picture. +- **Snake and goat pupils** are painted over the drawn round pupil, in the + iris's own middle tone, then the slit or bar on top. They are placed in + SCREEN space: several eyes were placed in the Loom with the oval turned + 90 degrees, and a slit that followed the oval's rotation came out sideways. +- **Blush and freckles** are multiplied onto skin that shows, the same mask as + the cast shadows, and placed from the eye placements, so no piece needs a + cheek or a nose marked. They share the skin overlay with the shadows. +- **Shine:** one clean ring across each crown piece (front hair, bangs), + measured along that piece's own crown line, crisp edged, in the hair's own + hue lifted toward white, on the fill only with the paper grain flattened. + Two attempts were rejected on the real art: a band broken along the strand + field read as salt drying on cloth, and one ellipse across the whole head + arched over every piece like a halo. Each piece takes its own ring. + The ring sits the same depth below every piece's top, set by the Shine at + slider (default 0.3, chosen on the purple short cut). It used to sit 22% of + each piece's own length down, which put a long piece's ring by the ear and + well below the fringe's. +- **Split:** the tips colour on one side of a line down through the crown. + The line and its wobble are measured on the frame, the same for every + piece. Each piece's own measure put the line somewhere different on each + piece, and the hair behind the bangs showed a wedge of the other colour. + Angle mode had the same fault and is now measured from the crown too. A + split or an angle ignores the bangs' hold-the-root-colour choice. + +**Cost bug:** blush and freckles first took 105s per share card. The skin masks +were untyped locals, so every pixel read in the overlay loop went through +reflection. With type hints the effects cost nothing measurable (3.4s, the +same as without them). + +**Art bug, ours:** a scratch copy of the art had every enclosed gap in the hair +filled white, from a test during the scalp work.
