Monochrome Minimal

Every texture is authored at the *exact* native pixel geometry of the vanilla
26.3 client, so the pack scales cleanly at every GUI scale setting with zero
layout drift. No `.mcmeta` sidecars are needed: all nine-slice scaling and
animation rules fall back to the vanilla defaults, and the artwork is drawn to
match them.

## What it changes

| Area | Result |
| — | — |
| Container screens | Solid black panels framed by a single clean white rule, with recessed black slot wells and matching white mechanics lines — covering the survival inventory, chests (`generic_54`), crafting table, furnace / smoker / blast furnace, enchanting table, anvil, smithing, brewing stand, hopper, dispenser, shulker box, loom, cartography table, stonecutter, crafter, beacon, horse, villager, the creative item tabs and the container progress sprites (flames, arrows, bubbles, experience bars, error marks, scrollers) |
| HUD | Health, hunger, armour, air, XP and jump meters drawn as white-to-gray lines, with a black translucent hotbar, a two-pixel white selection frame and matching off-hand slots |
| Crosshair | A single white dot with a soft dark halo, plus a clean white attack-cooldown ring and hotbar bar |
| Menus & widgets | Black sliders, buttons, text fields, checkboxes, tabs, scrollbars, tooltips, popups, list chrome, the recipe book, social-interaction controls and the friends list, plus black menu backgrounds and white separators |
| Typography | A re-authored pure-white bitmap font that reproduces vanilla’s clean sans-serif letterforms pixel for pixel, so text looks like ordinary Minecraft text at maximum contrast |
| Pack icon | `pack.png`, a black plate with a white dot reticle |

The only vanilla GUI textures the pack deliberately leaves alone are Mojang
branding artwork: the title logos and panorama, the Realms promo art and the
superflat preset thumbnails. Everything else in the vanilla GUI — including
the advancement tab tiles and the Realms status badges — is redrawn here.
